LMMSE Equalization Algorithm Research Based on 0.5chip Level

Article Preview

Abstract:

The LMMSE equalization filter based on minimum mean square error (MMSE) criterion can effectively suppress the inter-symbol interference caused by multi-path and recover the orthogonality among the spreading codes. In this paper, LMMSE equalizer with 0.5chip level algorithm is studied in the downlink of the UTRA HSPA+ system and the simulation results show that the performance of algorithm with 0.5chip level is better than the algorithm with one chip level.
