The authors present a multicarrier asynchronous direct sequence code division multiple access (DS-CDMA) system which uses an adaptive blind algorithm for the optimum combining of the desired signal contributions from different carriers. The output of the transmitter convolutional encoder modulates multiple band-limited DS-CDMA waveforms which are parallel transmitted with different carrier frequencies. The performance of this system is compared to that of a conventional single-carrier DS-CDMA system with a RAKE receiver and a RAKE receiver with a sliding window decorrelator filter. In this latter case, the RAKE receiver uses pilot symbols to track the channel impulse response time variations. The results demonstrate a performance similar to that of a decorrelating detector in the context of a severe near-far situation while exhibiting lower complexity
