Burst Channel Error Reduction Based on Interleaving for Efficient High-Speed Wireless Communication

Abstract

Recently, the demand for reliable and high-speed wireless communication has rapidly increased. Orthogonal frequency division multiplexing (OFDM) is a modulation scheme that is the newest competitor against other modulation schemes used for this purpose. OFDM is mostly used for wireless data transfer, although it may also be used for cable and fiber optic connections. However, in many applications, OFDM suffers from burst errors and high bit error rates. This paper presents the utilization of a helical interleaver with OFDM systems to efficiently handle burst channel errors and allow for Bit Error Rate (BER) reduction. The paper also presents a new interleaver, FRF, the initial letters of the authors’ names, for the same purpose. This newly proposed interleaver summarizes our previous experience with many recent interleavers. Fast Fourier transform OFDM (FFT-OFDM) and Discrete Wavelet Transform OFDM (DWT-OFDM) systems are used to test the efficiency of the suggested scheme in terms of burst channel error removal and BER reduction. Finally, the general complexity of the FRF interleaver is different from that of the helical interleaver in terms of hardware requirements. The performance of the proposed scheme was studied over different channel models. The obtained simulation results show a noticeable performance improvement over the conventional FFT-OFDM and the FFT-OFDM systems with the helical interleaver. Finally, the disadvantage of the proposed FRF interleaver is that it is more complex than the helical interleaver.

Second Order Statistics of -Fisher-Snedecor Distribution and Their Application to Burst Error Rate Analysis of Multi-Hop Communications

“…Moreover, the 5G and 6G systems add the ultra-reliable low-latency communication (URLLC) which demand the performance analysis with respect to time. Indeed, the burst error rate analysis over timevarying fading channels represents useful performance metrics for various 5G and beyond 5G communication scenarios [86]- [88]. The burst error rate analysis based on s-order statistics of dual-hop and multi-hop relay communications over cascaded Nakagami-m and Log-normal fading channels has been considered in [61] and [66].…”

A reduced complexity rate-matching and channel interleaver/de-interleaver for 5G NR

“…A versatile block interleaver designed for channel interleaving by simultaneously considering both time and frequency diversities is proposed targeting terrestrial broadcasting system in [21]. A configurable architecture proposed in [22] provides flexibility and improvement in reliability of data transmission. Eliminating intricate functions like mod and floor function, a cost effective and reconfigurable architecture for WiMAX, WLAN and Long-Term Evolution (LTE) in Third Generation Partnership Project (3GPP) standard has been discussed in [23].…”
