Analytical Evaluation of Iterative Packet Combining and Multipacket Detection Schemes for SC-FDE

Abstract

Packet Combining (PC) and Multipacket Reception (MPR) techniques have great potential to deal with lost packets since both take full advantage of the signals associated to all failed transmission attempts. However, their performance evaluation in practical systems is difficult because lengthy simulations are needed to obtain the packet error rates for specific channel conditions. The paper presents an analytical tool to obtain the Bit Error Rate (BER) and Packet Error Rate (PER) performances for Packet Combining (PC), Multipacket Reception (MPR) and the hybrid of both schemes, based on Iterative Block Decision Feedback Equalization (IB-DFE) receivers for Single-Carrier with Frequency-Domain Equalization (SC-FDE). A set of simulation results show that the proposed analytical approach has accurate Bit Error Rate (BER) and Packet Error Rate (PER)results with a simple and relatively fast method. 1

Packet combining based on cross-packet coding

“…Similarly, in [9], the authors propose a joint iterative decoding algorithm for turbo codes with packet combining. In [10,11], the authors focus on the theoretical evaluation of performance in applying packet combining ARQ technique in TDMA (time division multiple access) system and singlecarrier frequency domain equalization (SC-FDE) system, respectively. However, these packet combining techniques involve joint decoding of channel codes and packet combining, which will greatly increase the complexity of decoding.…”
