In this paper, performance of double binary turbo coded orthogonal frequency division multiplexing (OFDM) system is analyzed and simulated in power line communications (PLC) channel. In order to make power line channel environments, Bernoulli-Gaussian noise is considered. The performance is evaluated in terms of bit error probability. From the simulation results, it is demonstrated that the double...
In this paper, we propose and simulate double binary turbo code for high speed power line communication (PLC) system. In order to make power line channel environments, Bernoulli-Gaussian noise is considered. The performance is evaluated in terms of bit error probability. From the simulation results, it is demonstrated that the double binary turbo coding scheme offers considerable coding gain with...
In this paper, we analyze and simulate performance of space time block coded (STBC) binary pulse amplitude modulation-direct sequence (BPAM-DS) ultra-wideband (UWB) systems with double binary turbo code in indoor environments. The indoor wireless channel is modeled as a modified Saleh and Valenzuela (SV) channel, which is proposed as a UWB indoor channel model by IEEE 802.15.SG3a. From simulation...
In this paper, we propose and analyze an turbo coding scheme for optical CDMA systems. It is assumed that optical channel is an intensity modulated (IM) channel and direct-detection scheme is employed to detect the received optical signal. From simulation results, it is demonstrated that bit error probability (BEP) and throughput performance is substantially improved with the number of iterations...
In this paper, the performance of a double binary turbo coded space time block code-ultra wide band (STBC-UWB) system is analyzed and simulated in multi-user environments. From the simulation results, it is demonstrated that the double binary turbo coding technique offers considerable coding gain with reasonable encoding and decoding complexity. It is confirmed that the double binary turbo coding...
In this paper, we analyze and simulate the iterative decoding performance of space time block coded (STBC) pulse position modulation-time hopping (PPM-TH) ultra-wideband (UWB) systems in indoor environments. The indoor wireless channel is modeled as a modified Saleh and Valenzuela (SV) channel, which is proposed as a UWB indoor channel model by IEEE 802.15.SG3a. In order to reduce the iterative decoding...

In this paper, the performance of a non-binary turbo coded ultra wide band (UWB) system is analyzed and simulated in multi-user environments. A binary pulse position modulation-time hopping (BPPM-TH) UWB system is considered. The performance is evaluated in terms of bit error probability. Simulation results demonstrate that the performance of such a UWB system can be substantially improved by increasing...
