PSAIC decoder for space-time trellis-coded DS-CDMA system - Electronics Letters

چکیده
A per-survivor adaptive interference cancellation (PSAIC) decoder is proposed for group decoding of a space–time trellis-coded DS-CDMA system. To mitigate error propagation by tentative decisions, persurvivor processing is introduced to a group decoder with adaptive interference cancellation. It is shown that the proposed decoder outperforms conventional decoders without much increase of decoding delay and complexity.

Performance of Joint Multiuser Detection and Group Decoding for Trellis Coded DS-CDMA Systems
Optimal multiuser detection of trellis coded signals has prohibitive complexity. A suboptimal concatenated scheme consisting of a maximum a posteriori (MAP) multiuser interference (MUI) detector followed by a deinterleaver and a soft trellis decoder has recently received considerable attention in the literature [1]. We call this scheme Concatenated Multiuser Detector and Trellis Decoder (CMDTD)...
متن کاملIterative detection for space-time coded synchronous CDMA communication systems
An iterative receiver is proposed for the downlink of CDMA communication systems that employ both a convolutional channel code and a space-time trellis code to achieve transmit diversity in the presence of channel fading. The proposed iterative receiver operates by exchanging extrinsic information between the channel and space-time decoders in each iteration. Comparison of performance results, ...

The combination of space-time coding and multiuser detection is an effective way to increase the spechl efficiency of multiple access systems. In this paper we propose a new multiuser decoder for space-time coded asynchronous D S CDMA systems over Rayleigh fading channels. The proposed scheme is an extension of the one introduced in 111. Complexity is reduced exploiting the lact that the trelli...

We propose two classes of sub-optimum receivers for coded direct-sequence code-division multiple-access (DS/CDMA) systems based on a generalized transmitter model. Compare to the optimum detector with complexity grows exponentially with the number of active user, the proposed detectors have linear complexity and near-optimum performance. The first class is to remove the multiple-access interfer...

The throughput enhancement of Space-Time Spreading (STS)-based Multicarrier Direct Sequence Code Division Multiple Access (MC DS-CDMA) system is investigated in this paper. Variable Spreading Factor (VSF) is utilized to improve the data throughput of the system. In this contribution, an analytical approach is proposed to compute a new expression for the Bit Error Rate (BER) performance of t...
