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
of channel-

Description: An adaptive transmit diversity scheme with quadrant phase constraining feedback is proposed in this
paper. With simple linear operations at both transmitter and receiver, the proposed algorithm can achieve better
system performances with only 2M − 2 bits of feedback information for systems with M transmit antennas.
Theoretical performance bounds of the proposed transmit diversity scheme are derived. Simulation examples and
theoretical analyses show that the proposed transmit diversity scheme outperforms not only the conventional openloop
transmit diversity techniques, but also some closed-loop transmit diversity techniques with more information
transmitted in the feedback channel.-An adaptive transmit diversity scheme with quadrant phase constraining feedback is proposed in this

Description: The channel is modeled by adding the Gaussian noise and Rayleigh Fading. Different combining methods and relaying protocols are studied and compared in this project. We analyzed performance characterizations in terms of The Bit Error Rate and the Throughput. The relaying protocols considered are Amplify & Forward and Detect & forward out of which the Amplify and Forward showed better performance. Among the combining schemes, the Maximal Ratio Combining scheme showed better Bit Error Rate and Throughput curves. The network was also extended to a four node communication system with two relays which act as the distributed antennas. Thus using the distributed antennas we can provide the space diversity without need for physical arrays.
Index Terms: Cooperative Diversity, Fading channels, combining techniques,
transmission protocols, Relay channel, Bit error rate, Throughput, Amplify and forward, Detect and Forward.
