Application of AFSCC in TC-OFDM System of Ka Band
Huaxin Wu · Communications technology · 2008
A scheme adopting Adaptive Forward Sub-Channel Control (AFSCC) techniques in the TC-OFDM system of Ka band is proposed. The principle of the AFSCC is analyzed. An adaptive path gain update method is used. The transmission channel delay is estimated by using the MUSIC (Multiple Signal Classification) method and the adaptive estimator. System model is established,and simulation results show that,at the BER of 10-3,a SNR gain of 3.4dB can be abtained by adopting AFSCC.
