  Abstract

CL1(closed loop mode 1) is one of the closed loop transmit diversity schemes defined by 3GPP WCDMA and adjusts the relative phases of the transmitted signals at the two transmit antennas, thereby maximizing the power of the received signal at the user equipment. A key component of this scheme is to encode the phase difference between two received signals arrived at the user equipment via two different transmit antennas and to send it back to the base station. This paper proposes a new phase difference representation based on the adaptive delta modulation and compares its performance with the corresponding one of CL1. Computer simulations show that, in a slowly fading environment, the proposed scheme produces more realistic representation of the phase difference than the one of the CL1, resulting in a lower BER.
