Burst-by-Burst Adaptive Joint Detection CDMA

Burst-by-Burst Adaptive Joint Detection CDMA
Burst-by-Burst Adaptive Joint Detection CDMA
Adaptive Quadrature Amplitude Modulation (AQAM) is combined with Joint Detection Code Division Multiple Access (JD-CDMA) in order to increase the throughput of a communications system, while maintaining a target BER. The QAM modes are adaptively switched, by estimating the Signal to Interference plus Noise Ratio (SINR) at the output of the joint detection receiver. For an eight-user AQAM/JD-CDMA scheme, a BPS performance of about 3.5 bits/symbol is achieved at an average SNR of about 18 dB, with a BER of approximately 0.02%, when using three different modulation modes, namely BPSK, 4-QAM and 16-QAM.

Abstract

Adaptive Quadrature Amplitude Modulation (AQAM) is combined with Joint Detection Code Division Multiple Access (JD-CDMA) in order to increase the throughput of a communications system, while maintaining a target BER. The QAM modes are adaptively switched, by estimating the Signal to Interference plus Noise Ratio (SINR) at the output of the joint detection receiver. For an eight-user AQAM/JD-CDMA scheme, a BPS performance of about 3.5 bits/symbol is achieved at an average SNR of about 18 dB, with a BER of approximately 0.02%, when using three different modulation modes, namely BPSK, 4-QAM and 16-QAM.
