Blind Beamforming Using the MCMA and SAG-MCMA Algorithm with MUSIC Algorithm

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 240)


Satellite communication system does not use training sequence because the satellite communication channel is similar to the additive white gaussian noise (AWGN). But, in the mobile satellite communication environment, inter-symbol-interference (ISI) seriously occurs due to movement of receiver. We must use the blind equalization for remove the ISI in mobile satellite communication. Blind equalization techniques such as MCMA and SAG-MCMA is suitable for channel equalization in the mobile satellite environment. But equalization performance of blind equalizer were not as satisfactory as expected. In this paper, we propose a blind equalization technique based on coordinate change and beamforming method in order to improve the BER performance of receiver in mobile satellite communication. The simulation results show that the proposed scheme with coordinate change need to less SNR about 1 dB to satisfy BER performance (10-5).
