In wireless communications, diversity combining is often employed to alleviate the deleterious effect of fading channels. As a variant of generalized selection combining (GSC), output thresholded GSC (OT-GSC) was proposed to minimize the processing power. Although extensive simulations were performed to evaluate the performance of OT-GSC in the existing literature, analytical results may be desirable...
A novel diversity-multiplexing decision switched algorithm is proposed for multiple-input multiple-output (MIMO) system based on variable-rate MQAM. The proposed scheme is a closed-loop system, achieves adaptive bit and power allocation according to real-time channel state information (CSI), and the tradeoff between the diversity and multiplexing gains that can simultaneously achieved over a low-rate...
Power line communication for home networking is a new convenient method. However, power line communication makes degradation because of the impulsive interference generated by electrical appliances. Therefore, it is the first problem we need to be solved. In this paper, we apply LDPC (low density parity check) codes to AWAN (additive white class a noise) channels which is usually used as the model...
A novel switched scheme is proposed for diversity-multiplexing switched multiple-input multiple-output (D-M MIMO) system under Raleigh fading based on bit error rate (BER). The proposed scheme is a closed-loop multiple antenna system, and the tradeoff between the diversity and multiplexing gains that can be simultaneously achieved over a low-rate limited feedback channel. Furthermore, based on the...
Recently, a combined transmitter-selection combining/ receiver-maximal-ratio-combining (TAS/MRC) scheme has been proposed to reduce the complexity of system and retain the diversity advantage. An accurate bit error rate expression is derived for arbitrarily correlated Nakagami fading channels. The Gauss-Laguerre quadrature based numerical method is employed to evaluate the derived expression. For...
Recently, a combined transmitter antenna selection/receiver-maximal-ratio-combining (TAS/MRC) scheme has been proposed to reduce the complexity of system and retain the diversity advantage. In this paper, we investigate the performance of the TAS/MRC scheme over correlated Nakagami fading channels. The characteristics function method is used to derive an exact bit-error rate expression, in which only...
