Abstract
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-of-band (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.
