Our aim is to improve both the convergence speed and the bit error rate (BER) performance of the conventional blind adaptive MMOE receiver in asynchronous AWGN channels. The proposed receiver structure makes use of the available knowledge of all users' spreading codes (i.e., at the base-station) to cancel multiple access interference (MAI) using a combined adaptive MMOE-PIC algorithm. It is shown that the proposed algorithm can significantly reduce the long training period requirement of the conventional adaptive MMOE receiver due to both the asynchronous transmission and the near-far problem. The BER of the proposed system is evaluated using the Gaussian approximation. Moreover, the performance of the proposed algorithm is compared with the conventional blind trained method. Both numerical and theoretical results show that the proposed receiver performs close to the standard minimum mean-squared error (MMSE) receiver whereas the adaptive MMOE detector suffers from a higher BER due to the imperfect filter coefficients.","PeriodicalId":201962,"journal":{"name":"2004 IEEE 15th International Symposium on Personal, Indoor and Mobile Radio Communications (IEEE Cat.

Two design structures are considered: the so called \"separate detection\" consists in using a particular adaptive filter structure for each carrier, whereas the so called \"joint detection\" is based on a joint structure defined by the concatenation of the adaptive filter weights dedicated to each carrier. We carry out a comparative study between both structures with various adaptive filters such as recursive least square (RLS), Normalized least mean square (NLMS) and affirm projection algorithm (APA). The simulation results show that a compromise has to be found between performance and computational cost. The so called \"joint detection\" scheme provides the best performance in terms of bit error rate (BER). Although NLMS has the lowest computational cost, it is outperformed by APA and RLS when considering the convergence rate or/and excess mean square error. Besides, the RLS provides the best performance but at the price of high computational complexity. Therefore, we propose to use APA in a joint structure to design the receiver.","PeriodicalId":201962,"journal":{"name":"2004 IEEE 15th International Symposium on Personal, Indoor and Mobile Radio Communications (IEEE Cat.
