Description: (书)现代通信系统使用MATLAB第三章-ALLIANCES is a recently proposed cooperative random access
protocol for wireless networks. In this paper we modify the
original model to include user location information. We also
derive pair-wise error probability (PEP) under Rayleigh flat
fading channel and a power-law attenuation environment.
Based on the PEP analysis we propose an optimal relay
selection scheme, which achieves significant throughput gains as
compared to the random relay selection scheme in the original
ALLIANCES. Platform: |

Description: 通过MATLAB软件；通过仿真得出性能曲线；从而比较bpsk的性能-The bit-error rate (BER) of binary phase-shift keying
in Rayleigh fading, using the Alamouti transmission scheme and
receiver selection diversity in the presence of channel-estimation
error, is studied. Closed-form expressions for the BER of log-likelihood
ratio selection, signal-to-noise ratio (SNR) selection, switchand-
stay combining selection, and maximum ratio combining are
derived in terms of the SNR and the cross-correlation coefficient
of the channel gain and its corrupted estimate. Two new selection
schemes, space–time sum-of-squares combining selection diversity
and space–time sum-of-magnitudes selection diversity, are
proposed and proven to provide almost the same performance as
SNR selection, but with much simpler implementations. The effects

Description: LDPC码是通过校验矩阵定义的一类线性码，为使译码可行，在码长较长时需要校验矩阵满足“稀疏性”，即校验矩阵中1的密度比较低，也就是要求校验矩阵中1的个数远小于0的个数，并且码长越长，密度就要越低。
-LDPC Coding with PSK modulation in Rayleigh fading channel
Most of the functions are built in matlab functions found in the comm. toolbox. These can also be easily configurable in the code to meet your requirements.
