“…Through the theoretical analysis of BPSK and QPSK and the comparison of error performance, QPSK modulation has higher accuracy than BPSK [5]. At the same time, the bit error rate performance of different arrays of QAM modulation technology in Rayleigh fading and additive Gaussian white noise channels is compared with QPSK, and it is found that QPSK has the best bit error rate performance in OFDM systems [6].…”

The transmission of communication signals must not only ensure the speed of transmission, but also ensure the accuracy of transmission. The current research has been able to draw the advantages and disadvantages of the application of different error-correcting codes. However, it is not enough to simply compare transmission performance between different error correction code applications. Therefore, this paper uses MATLAB to simulate the transmission environment of the real channel, analyzes the reception error of short-length data through QPSK coding and IQ modulation, and analyzes the signal transmission using error correction code (Hamming code) and error detection code (even check code). The transmission performances were explored and compared, and their anti-noise interference performance was analyzed. Studies have shown that for short-length data, the error correction method using Hamming code can resist limited noise interference, but it can save bandwidth and increase the proportion of effective signal bits. In the low signal-to-noise ratio case, the method of using even-check code to detect errors has problems. Errors may be generated, and the proportion of effective signal bits is low, but the adaptability to noise is stronger than the previous method. Therefore, it is recommended to select different transmission methods for transmission environments with different signal-to-noise ratio ranges, and the combination of the two may further improve the anti-noise interference capability of signal transmission.

“…Moreover, Weightless-P's GMSK and QPSK modulation are improvements over Weightless-N's DBPSK. But QPSK has a higher error rate and requires more power to lower this [71], [72] while the use of GMSK also lowers Weightless-P's effective range and makes it potentially less suitable for use in WANs. Weightless SIG have also taken effort to ensure the standard achieves the best performance within ETSI and FCC regulations.…”

Previous survey articles on Low-Powered Wide-Area Networks (LPWANs) lack a systematic analysis of the design goals of LPWAN and the design decisions adopted by various commercially available and emerging LPWAN technologies, and no study has analysed how their design decisions impact their ability to meet design goals. Assessing a technology's ability to meet design goals is essential in determining suitable technologies for a given application. To address these gaps, we have analysed six prominent design goals and identified the design decisions used to meet each goal in the eight LPWAN technologies, ranging from technical consideration to business model, and determined which specific technique in a design decision will help meet each goal to the greatest extent. System architecture and specifications are presented for those LPWAN solutions, and their ability to meet each design goal is evaluated. We outline seventeen use cases across twelve domains that require large low power network infrastructure and prioritise each design goal's importance to those applications as Low, Moderate, or High. Using these priorities and each technology's suitability for meeting design goals, we suggest appropriate LPWAN technologies for each use case. Finally, a number of research challenges are presented for current and future technologies.

Software Defined Radio (SDR) has the flexibility to modify the characteristics of the receiving and transmitting radio device, without physically adjusting the hardware, due to development in the system. Because of the increasing need for wireless communication applications so as to enable consumers to communicate anywhere through information led to the emergence of many communication devices to include the large amount of applications that every one of the devices needs power and thereby increase the total power. This study confirms that the wireless communication system for secured transmit data, fast and inexpensive; can be done by implementing using Partial Reconfiguration (PR) modern technology in FPGA developing based on SDR. The Speed and performance can be improved. The area also can be decreased. The new Xilinx, Vertex Series FPGA, provides the provision of PR. The power consumption can be reduced by applying power reduction techniques in the blocks. The combination of MATLAB (Simulink and M-file) and Simulink HDL Coder offers flexible capabilities for analysis, design; simulation, implementation, and verification. With all these capabilities, in a single system to reduce the time spent tuning for reducing the algorithms and models during rapid prototyping and experimentation and less time on HDL coding. Contribution/ Originality: This study contributes in the existing literature review for implementing MC-CDMA wireless communication system using Partial Reconfiguration (PR) that is a new technology in FPGA. 1. INTRODUCTION The wireless communications revolution started with the mobile phone at the beginning of the 80's and all the improvements which have led to the multiplication of mobile and wireless communications networks and standards [1]. The 1st Generation (1G) of technology was characterized by analog means voice only; 1G quality was too low and also had connections to low speed, but they effectively offered the inherent easiness of mobile communications. The system used in 1G was Frequency Division Multiple Access (FDMA) [2]. The 2nd Generation (2G) of technology is digital in the United States, most of the devices and services were digital. The spread of digital mobile
