“…Ya en otras investigaciones se ha analizado sobre como la velocidad máxima de transferencia de datos influye en el ancho de banda para sistemas SDRadar [18], [19], en este caso para USRP B210 se tiene una velocidad de transferencia de 50 Mbps, sin embargo, debido a que la USRP utiliza muestras complejas I/Q, el ancho de banda B con el cual se puede trabajar es de 25 MHz. Al reemplazar el valor de ancho de banda en (2) se obtiene ∆R = 6 m.…”

Abstract-This paper analyzes the universal software radio peripherical (USRP) B210 limitations and characteristics to develop applications on Software Defined Radar (SDRadar). The developed algorithm uses a frequency modulated constant wave (FMCW) which implement a chirp signal, taking considering that 25 MHz is the maximum bandwidth that the USRP can provide with a maximum resolution of 6 meters. The method improves the resolution through several signals transmitted with different bandwidths obtaining different resolutions, which were stored in a simple matrix and analyzed. After simulations, it is determined that the 14 measurements done with bandwidth spacing of 0.5 MHz between every signal is the best way to improve the resolution. Finally, two scenarios are described for the optimization procedure, the first scenario is limited with a measurement error less than 1 meter and the second scenario is limited by measurement error between 1 and 2 meters getting a better effectiveness of the measurement under the first scenario with 69.15% of detected objectives compared with the 30.85% of effectiveness of the second one. This paper demonstrates that the algorithm used is useful on SDRadar applications to detect objectives, for topographic applications or SAR systems.

Para el desarrollo del algoritmo se utilizó un radar de onda continua modulada en frecuencia (FMCW) que implementa una señal chirp, al considerar que 25 MHz es el máximo ancho de banda que la tarjeta puede proporcionar se obtiene como resultado una resolución de 6 metros. El método utilizado para optimizar la resolución de la tarjeta fue transmitir un determinado número de señales con distintos anchos de banda, lo que resulta en una resolución diferente, al detectar y almacenar el objetivo en una matriz. Después de las pruebas correspondientes el algoritmo estableció que con 14 mediciones con variaciones de ancho de banda de 0.5 MHz, entre cada señal, se obtiene la mayor optimización para mejorar la resolución de la tarjeta. Se obtuvo finalmente dos zonas de optimización, donde la primera zona está limitada por un error de medición menor a 1 metro, y en la segunda zona con un error de medición entre 1 y 2 metros con 69.15% y 30.85% de objetivos detectados respectivamente, lo que determina su efectividad y confiabilidad. Este trabajo ha demostrado que el algoritmo utilizado es útil en aplicaciones SDRadar para detectar objetivos para aplicaciones topográficas o sistemas SAR. Uno de los inconvenientes de la tecnología SDR, es el ancho de banda que proporcionan para ser aplicados en sistemas SDRadar, que es una característica importante que depende de la capacidad de detección de dos objetivos o blancos en el rango, lo que es mejor conocida como resolución.

“…Many efforts have been established by researchers to construct USRP as software defined radar with various radar types. The most common one is frequency modulated continuous wave (FMCW) radar as done in [1], [4]˗ [6]. In general, the USRP has well performance under FMCW to detect target with limited distance due to the constraint on its output power.…”

Abstract— Radar or radio detection and ranging has a basic function to detect and measure a target range. One of the latest developments is Software Defined Radio (SDR)-based radar. An example of SDR implementation is by using Universal Software Radio Peripheral (USRP) as hardware and GNU Radio Companion (GRC) as software. The simplest radar type is pulse radar in which system timing is crucial. Meanwhile, in pulse radar system implementation using USRP and GRC, there is an issue with the random processing time delay between communication protocol of USRP and computer running the GRC, which causes incorrect measurement. This research aims to analyze the random time delay in the pulse radar system implementation by using USRP and GRC to anticipate the effect of random time delay. Pulse radar systems implementation is administered by transmitting 128 bits of Barker code and performing correlation between transmitted and received radar signal. Research result shows that the random time delay can be anticipated by making the direct reception from radar transmitter to receiver as the reference in range calculation.

“…transmission coding, receiver decoding, FSK modulation, filtering, etc. ), except from the led driver in the transmitting stage and the trans-impedance amplifier in the receiving stage, have been implemented via software, in order to make the system as much flexible and low cost as possible, following a Software Defined paradigm, widely used in current literature in the framework of radio and radar systems [7] and [8] . Since all VLC system performances extremely depend on external light conditions, in order to properly face with environmental luminosity changes (e.g.…”

Abstract. In this work, we propose a Visible Light Communication (VLC) system dynamically adapting, through a decision-making process based on a simple fuzzy-logic, the transmitting color selection to the external environmental conditions. Transmitted Signals are opportunistically treated through softwarization approaches by using basic hardware (i.e. Arduino boards and inexpensive LEDs in the transmitting stage) in order to implement an effective, end-to-end, adaptive communication system. In particular, we will show that, if a low environmental noise is added, the system keeps to be well-performing in terms of Bit Error Rate (BER) also at higher distances (up to 8-9 meters) using a warm white front-end, while, if high external interfering lights are present in the environment, a low power red front end is dynamically fed for maintaining a good-level communication (with low Bit Error Rate).
