This paper proposes an error control mechanism for data transmission defined as simple Hybrid Automatic Repeat-reQuest (ARQ) utilizing Bit-Interleaved Coded Modulation (BICM). The study investigates the Bit Error Rate (BER) performance of wireless communications using high rate Hybrid ARQ enabled by the proposed Bit-Interleaved Coded Modulation with Iterative Decoding (BICM-ID) option. The Incremental...
A frequency division multiplexing technique, nonorthogonal frequency division multiplexing (n-OFDM), is proposed in [1]– [2] to enhance the efficiency of bandwidth utilization. This paper reveals that the smaller the frequency separation, the larger sum capacity can be achieved compared with the conventional OFDM technique. However, n-OFDM system introduces inter-carrier interference (ICI) at the...
Ultra wideband (UWB) system requires high data rate transmission for a short wireless link application. The application of turbo codes in the system will improve the bit error rate (BER) performance. In this paper, the analysis of recursive systematic convolutional (RSC) turbo codes in the multiband orthogonal frequency division multiplexing (MB-OFDM) will be investigated in UWB channel with channel...
