| 摘要 | This paper presents new transceiver framework for the DS-CDMA systems that use the multiple-input multiple-output (MIMO) antennas, with space-time block code (ST-BC). In the transmitter, new hybrid (prefix/postfix) zero-padding sequences combining with the desired user signature is exploited to form the hybrid augmented user signature sequences, with respect to different transmit-antennas. While in the receiver under the GSC framework a new Capon-like semi-blind MIMO-CDMA filterbank detector based on the linearly constrained constant modulus (LCCM) criterion, is derived. Also, the adaptive GSC-RLS algorithm is developed for adaptively implementing the blind LCCM MIMO-CDMA filterbank of the receiver. With the specific design of the hybrid augmented user signature sequences, we are able to resolve phase ambiguity problem of blind channel estimation. Computer simulations verify the merits of the proposed new transceiver framework; it can be employed to achieve better performance, and is more robust against the discrepancy due to Capon channel estimation. |
