SIR Analytical Expression for Dispersive Channels in OFDM/OQAM Transmission Systems

International audienceIn this paper, we derive the analytical expression of the signal to interference ratio (SIR) for orthogonal frequency division multiplexing with offset quadrature amplitude modulation (OFDM/OQAM) systems, in time and frequency dispersive channels. In this derivation, we use the dispersive approach, which is based on using a matched filter and provides optimal reception. Finally, we search optimal transmitter prototype function s that maximize the SIR

Optimization of the PHYDYAS Waveforms Using the POPS Algorithm: POPS-PHYDYAS

International audienceOrthogonal Frequency Division Multiplexing (OFDM) was adopted by the fourth generation (4G) of mobile communication systems to guarantee high data rates with high terminal mobility. However, OFDM ensures strict synchronism and orthogonality, which reduces the throughput and energy efficiency of the communication networks. With the advent of 5G cellular wireless communication systems, the use of non-orthogonal multiplexing schemes, which preserves the OFDM benefits without requiring high-level synchronization, becomes an important research topic. Recently, the POPS algorithm [1] has been introduced as a powerful tool to efficiently design waveforms candidates for 5G. In this paper, we propose a new design of PHYDYAS waveforms namely POPS-PHYDYAS. It is based on the mix of the POPS algorithm and the PHYDYAS filter [2]. The results confirm the advantage behind the POPS-PHYDYAS algorithm in enhancing the performance compared to multicarrier systems using the original PHYDYAS waveforms, as they are conceived by Mirabbasi-Martin [3]. Simulations are given to support our clamis
