| Abstract: | The arraying combining performance in deep space network is seriously affected by interference signals.The SNR formula of the combining signal with interference signals is derived.The phase residual estimate algorithm is analyzed by use of the cyclic cross-correlation,and another estimate algorithm of BPSK signals is presented based on the cyclic auto-correlation.The two methods are firstly used in the arraying signal combining.Theoretical analysis and simulation results show that both the two methods have ... |
