Main research staff: Chen Shangqin Li Xiaofeng Luo Chenglie Li Xu Liu Qiwu Adaptive Equalization and Detection Techniques In the adaptive equalization algorithm, the improved FTF fast algorithm, eliminating the length of the positive feedback and other limitations, using a higher sampling rate and improve the synchronization accuracy; The receiving end adopts the carrier pre-tracking and phase-locked phase synchronization scheme to improve the reliability and fast tracking ability and develop a simple means of observing the waveform of the key point. The provided serial system scheme, for the short-wave average characteristic channel, the bit error rate in the absence of error correction code reaches 10 to 3 orders of magnitude than the parallel system
