This is unscented kalman filter and particle filter matlab algorithms.

In this simulink model , baseband 8-ary PAM detection is simulated .A half-sine pulse shaped PAM signal is given as input to the detector.The received signal is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The 8-ary PAM signal transmitted is recovered at the detector output.

CSMA/CD(1-persistent): 当有packet需要发送时： • 如检测到信道空闲，发送packet • 如检测到信道忙，一直检测信道状态，一旦信道空闲，立即发送(CSMA/CD (1-persistent): When there is packet needs to be sent when: • If the channel is detected idle, transmit packet • If the channel is detected busy channel state has been detected, once the channel is idle, transmit immediately)

This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).
