Time division duplex technique for power control in selection diversity reception direct sequence spread spectrum communications

A time division duplex (TDD) direct sequence spread spectrum communication (DS-SS) system is proposed for operation in multipath Rayleigh fading environments such as indoor communication channels. It is shown that utilising the TDD technique is advantageous for various reasons such as the simplification of the DS-SS transmitter and receivers, more efficient frequency bandwidth utilisation and the realisation of a simple but efficient power control technique. Computer simulation results show the superiority of the power control method. An efficient power control method will result in higher capacities for the system.<
