“…The authors have characterized different waveform candidates based on their resulting BER and Adjacent Channel Power Ratio (ACPR) taking into account power amplifier nonlinearities. A hardware testbed has been presented in [3] which has been used to conduct asynchronous multiple access experiments using multiple transmitters. It has been shown that OFDM is less robust under lack of synchronization, and waveform candidates such as UFMC and FBMC have shown improved performance in terms of BER.…”

A software defined radio (SDR) approach to demonstrate the coexistence in Machine Type Communication (MTC) scenarios is presented. MTC in recent years has gained significant attention with its inclusion in the 5G business model. Spectrally efficient asynchronous communication is a key enabler in situations involving MTC. Past research has shown that some modifications to baseline cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) can achieve better out-ofband (OOB) suppression and enable asynchronous coexistence. Inspired by this research, we provide a real world example of coexistence using SDR. We demonstrate the ability to asynchronously transmitting waveforms in adjacent channels with very narrow guard bands in between, and still be able to receive and demodulate them with low error vector magnitude (EVM) and low bit error rate (BER) that are comparable to the baseline CP-OFDM that uses synchronous communication.

Ultra-reliable V2V communications with extreme transmission rate probably constitute the most ambitious use case of the fifth generation mobile. At present, both the scientific community and the standardization bodies are addressing the design of the technologies that will make it possible, although there is no unanimity in which technologies to incorporate. This paper approaches this topic from the work developed in the METIS-II project, describing the use case, the technology enablers and some details of the evaluation of these techniques in realistic scenarios. Results show that, for a baseline system, carrier bandwidths needed to fulfil the requirements are between 30 and 100 MHz, depending on the scenario. Nevertheless, results show potential to reduce the needed bandwidth to a range between 20 and 50 MHz by incorporating additional technology enablers to the studied baseline system.

“…So far, many experimental testbeds including multiple waveforms have been developed [11][12][13][14][15][16]. However, they mainly focus on dedicated implementations for isolated waveforms, without considering a versatile implementation able to generate different waveforms according to a harmonized framework with hardware reuse.…”

The coexistence of multiple air interface variants in the upcoming fifth generation (5G) wireless technology remains a matter of ongoing discussion. This paper focuses on the physical layer of the 5G air interface and provides a harmonization solution for the joint implementation of several multicarrier waveform candidates. Waveforms based either on cyclic prefix-orthogonal frequency division multiplexing (CP-OFDM) or on filter bank multicarrier (FBMC) are first presented through a harmonized system model. Complexity comparisons among five different waveforms are provided. Then, the complexity of a proposed configurable hardware implementation setup for waveform transmission and reception is evaluated. As a result, the harmonized transmitter and receiver exhibit 25-40% and 15-25% less complexity in floating-point operations, respectively, in comparison to two standalone implementations of the most complex waveform instances of the CP-OFDM and FBMC families. This highlights the similarities between both families and illustrates the component reuse advantages associated with the proposed harmonized solution.
