BCH_bpsk code in matlab generation
no vote
This codepresents the performance evaluation and comparison of various concatenated error correcting codes using Binary Phase Shift Keying (BPSK) modulation scheme. Three concatenated error correcting code pair i.e. Convolutional-Hamming, Convolutional-Cyclic, Convolutional-Bose, Chaudhuri Hocquenghem is designed and the BER performance was measured for an Additive White Gaussian Noise (AWGN) channel. All pairs of concatenated codes have been compared in terms of bit error rate & energy per bit to noise power ratio and their performance reflects their error correcting capability. All simulation was done using MATLAB R2009a Simulink software. In general Convolutional-Bose Chaudhuri Hocquenghem demonstrate better performance compared to Convolutional-Hamming and Convolutional-Cyclic concatenation pairs. Keywords: Additive White Gaussian Noise (AWGN) ,

LDPC code by matlab ldpc generation
no vote
Low-density parity-check (LDPC) coded is a suitable coded modulation technique for optical communication Compared to single carrier, it is more robust to chromatic dispersion (CD) and polarization mode dispersion (PMD). Recently, there have been quite a few experimental demonstrations using LDPC-coded, coherent optical OFDM (CO-OFDM) for high speed long-haul transmission. However, CO-OFDM is prone to linear phase noise caused by both transmitter laser and receiver local oscillator. LPN will cause both common phase error (CPE) and intercarrier interference (ICI) in the frequency domain. ICI can be approximated as additive white Gaussian noise (AWGN) and is negligible when the laser linewidth is small. Pilot subcarriers or pilot-tone have been proposed for CPE estimation.
