... improved at the cell border. By using the CAT, the MT exploits the addi- tional transmit diversity where the maximum is given at the 6 EURASIP Journal on Wireless Communications and Networking at the ... from the desired base station and the other base station. This ratio also indicates where the mo- bile user is in respect to the base stations. For...
