The first experimental demonstration of nonbinary-LDPC-coded optical transmission is presented. Using DQPSK, we can achieve >;8dB and ~10dB net coding gains at the BER of 10-6 in the absence and presence of I/Q imbalance, respectively.
This paper presents the first analysis on the energy efficiency of LT codes with Non-Coherent M-ary Frequency Shift Keying (NC-MFSK), known as green modulation, in a proactive Wireless Sensor Network (WSN) over Rayleigh flat-fading channels with path-loss. The current analysis is based on realistic parameters in the IEEE 802.15.4 standard including the effect of channel bandwidth and active mode duration...
This paper focuses on the applicability of bit-interleaved space-time coded modulation with iterative decoding (BI-STCM-ID) to wireless local area networks (WLAN). A new intuitive space-time diversity scheme, which ensures a low error rate for small signal-to-noise ratios (SNR) and good asymptotic performance, is provided. The presented technique can ensure compatibility with todaypsilas WLAN specifications...
Linear precoded discrete multitone modulation (LP-DMT) system has been already proved advantageous with adaptive resource allocation algorithm in a power line communication (PLC) context. In this paper, we investigate the bit and energy allocation algorithm of an adaptive LP-DMT system taking into account the channel coding scheme. A coded adaptive LP-DMT system is presented in the PLC context with...
