Abstract

Two code timing acquisition algorithms for MIMO-CDMA system are proposed. While in the conventional methods v pilots are transmitted continuously, in the proposed algorithms, pilots are cyclically transmitted over each transmit antenna, so that it is very efficient with respect to code scarcity problem. At receiver code timing acquisition is acquired by giving estimated delays the weighted average, which is in proportion to the peak of the output obtained from matched filter of each channel. Simulation results show that the proposed methods give better code timing acquisition performance than the conventional method.
