基于WRELAX的小运算量GNSS多径干扰抑制算法
GNSS Multipath Mitigation Algorithm with Low Computation Burden Based on WRE-LAX
摘要
Abstract
The paper studied the multipath interference mitigation in global navigation satellite system (GNSS) .A novel efficient weighted RELAXation (WRELAX) based algorithm considering the charac-teristic of the correlation of GNSS signal is proposed .The proposed algorithm has the advantage of lower computation burden compared with the state of art methods .In the proposed algorithm ,by windowing the auto-correlation of the reference signal and the cross-correlation between the received data and the lo-cal reference signal ,the data length in the iterative parameter estimation process is greatly shortened . Therefore ,the amount of computation burden is reduced .Experimental results indicate that the proposed algorithm has similar performance and much low computation burden compared with the original WRE-LAX algorithm .关键词
