Abstract

In order to improve the transmission performance in intersymbol interference (ISI) channel, high rate lower-order modulation transmission employing ISI is studied and the error rate performance of lower-order modulation and higher-order modulation are compared. Since high rate lower-order modulation transmission employing ISI makes full use of the potential anti-jam capability of the system, the threshold signal to noise ratio is greatly decreased by more than 10 dB. Simulation results show that lower-order modulation transmission, which is interfered by ISI and employs sequence detection, obtain great performance gain according to higher-order modulation, which is not influenced of ISI and detected symbol by symbol.
