A New Cooperative Diversity Protocol for CDMA Signaling Using Complete Complementary Codes
نویسندگان
چکیده
This paper develops and analyzes a new class of detect-and-forward cooperative diversity protocols adopting complete complementary code sets spreading. The proposed protocol employs a multi-band DS-CDMA transmission tailored to their distinct correlation properties. The complete complementary codes sets have an impulsive autocorrelation sum among each set and orthogonality between respective codes in different sets. The new protocol is shown to be advantageous due to the efficient assignment of the spreading codes through the transmission bands, receiver simplicity, and being applicable to several wireless CDMA systems. The protocol is compared to non-cooperative multi-band DS-CDMA system and illustrates enhanced performance under the effect of AWGN and a single path quasi-static frequency non-selective Rayleigh fading channel.
