| Abstract(in English) | This paper proposes and evaluates a new diversity technique for the reverse link of IS-95 based CDMA systems. The proposed diversity technique utilizes time correlation of fading channels by transmitting multiple orthogonal sequences in parallel. However, this system does not require any additional redundant channels for parallel transmissions of orthogonal sequences. From results through theoretical analysis and computer simulation, the proposed system improves BER performance, and reduces the required E_b/N_0 by ore than 1dB at BER=10^-5 in Rayleigh fading environments with the Doppler frequencies of 50Hz to 250Hz. |
