“…IDFT is the main block that should be bypassed at the receiver when not required (Turbo-FSK, OFDM). Since FFT and IDFT modules are highly optimized for implementation, these blocks have often limited complexity impact on the design [12]. This preliminary analysis should however be confirmed by a more hardware complexity thorough study.…”

In the context of Low Power Wide Area (LPWA) networks, terminals are expected to be low cost, to be able to communicate over a long distance, and to operate on battery power for many years. In order to support a wide range of LPWA applications, the next generation of LPWA technologies is expected to provide faster throughput, be more resilient, and guarantee lower levels of latency for a similar battery lifetime. These contradictory requirements, lead to consider the design of a flexible physical layer with the aim to be efficient for the identified operating modes from "low data rate, low power consumption, long range" to "high data rate". Performance of waveform candidates is assessed in terms of PER, range and also power consumption in order to obtain the best compromise between operating modes. A new flexible waveform based on frequency domain processing is finally proposed to address the large scale of requirements of new LPWA applications.

“…Thus, with a specific parameterization we can address different modes from low data rate with low power consumption to high data rate. Although the complexity introduced by the multiple modes is not analyzed, the flexibility introduced by the approach should not lead to significant complexity overhead: hardware complexity of a physical layer is often dominated by the complexity of modules such as FFT and IFFT that can be highly optimized [7].…”

Future Low Power Wide Area (LPWA) systems are expected to provide support for a wider range of applications: faster throughput and performance for lower levels of latency is hence forecast for a similar battery lifetime. These contradictory requirements lead to consider a flexible physical layer operating for different modes from low data rate, low power consumption, long range to high data rate. This new flexible physical layer approach is presented in this paper: simulation performance is given and compared to field trial measurements using a software defined radio implementation. Finally, field measurement comparison to state of the art LoRa is performed. The paper demonstrates with these measurements some practical benefits of the new approach.

“…The proposed system was implemented by using an FPGA Kintex-7XC7K325T. Finally, the authors have concluded that FBMC outperforms OFDM for high order modulation scheme (Berg et al, 2014b). The authors of this work ha compare FBMC and Cyclic prefix based OFDM to evaluate the BER probability under an AWGN channel and conclude that the performance of both systems is similar when all conditions is satisfied, however FBMC gives less out band power leakage as compare to OFDM (He and Schmeink, 2015).…”

By the year 2020, the data traffic can be approximately increase by 30%, which cannot support by existing mobile technologies. Hence, there is a requirement of next generation wireless communication (5G) which aim to provide a high capacity, data-rate at the speed of 1Tbps. By selecting a better modulation technology, the required capacity and datarate can be achieved. In this study we design aprototype filter for multicarrier modulation candidates of 64-subchannels for 5G mobile communication system: Orthogonal Frequency Division Multiplexing (OFDM) often used in 4G mobile and Filter Band Multi-Carrier (FBMC) a promising candidate for 5G mobile communication system. We judge the magnitude response of prototype filter for OFDM and FBMC. Magnitude response for overlapping factor (K = 2, 3, 4) is also evaluated. Finally the constellation plot clearly defines the transmission scheme of FBMC and OFDM. FBMC proof to be preeminent method and outperforms OFDM due to the fact that FBMC do not use (CP) cyclic prefix and wide guard band un-like OFDM.
