Abstract
This paper studies a novel cooperative transmission scheme that allows single-antenna users to benefit from spatial diversity for the uplink of TDD-CDMA systems. In such systems, the chip-synchronous transmission is attainable and thus, using orthogonal spreading codes can completely eliminate MAI in flat Rayleigh fading channels plus AWGN and make the user-cooperation possible. The proposed cooperation scheme is applicable to any constant-envelope modulation and achieves the fullest diversity order, the low implementation complexity and the full data rate. The closed-form outage probability expression was also derived to verify its validity. A variety of numerical results reveal the cooperation significantly outperforms non-cooperative counterpart under the same transmit power constraint.
