Improved Data-aided Receiver for High-speed Mobile Environment
In order to ensure service quality of communication in high mobile speed, the improvement of receivers performance is of great importance. The paper takes high-speed communication as the researching background. Algorithms for equalizing intersymbol interference and Doppler Effect are studied for dataaided transmission. The inputs of equalization are improved by the mended derotation method. Take frequency deviation introduced by Doppler Effect and receiver itself into consideration, a cascade structure of frequency estimation and compensation for equalization algorithm is proposed. Simulation results show that the method promote the performance of the system well.
