The process of turbo-code decoding starts with the formation of a posteriori probabilities (APPs) for each data bit, which is followed by choosing the data-bit value that corresponds to the maximum a posteriori (MAP) probability for that data bit. Up

In the orthogonal frequency division multiplexing communications, bit flipping can be used for the reduction of peak-to-average-power ratio (PAPR). Error-correction coding can be used to relieve the degradation of bit-error rates (BERs) resultant fro

Outer Reed Solomon (RS) Code was proposed in [1] and further analyzed in [2]. The following results are based on simulator [2] analyzing the influence of different performance metrics, MCS, and channels: * PER/Throughput vs. Eb/N0 or SNR: * BPSK/QPSK

In this letter, we propose and experimentally demonstrate an underwater wireless optical communication system based on a simple and cost-effective TO56 transversal multi-mode green-light laser diode (LD) and a low-cost 150-MHz positive-intrinsic-nega

Online bit error rate (BER) estimation (OBE) has been used as a stopping iterative turbo decoding criterion. However, the stopping criteria only work at high signal-to-noise ratios (SNRs), and fail to have early termination at low SNRs, which contrib

A new scheme, called code index modulation-spread spectrum (CIM-SS), is presented in this paper. This scheme is based on direct sequence-spread spectrum (DS-SS) modulation and can achieve higher data rate than the conventional DS-SS with lower energy
