In this paper, we study the performance of an antenna switching (AS) system in a multipath Rayleigh fading channel in comparison to an Alamouti coded system. We propose a minimum mean-squared error based iterative equalizer for the multi-antenna system. In the proposed receiver, MMSE equalization and channel decoding are jointly carried out at each iteration by using the a priori probabilities from...
When channel state information is not available, combined unitary space-time modulation and parallel concatenated convolutional code can greatly improve the system performance, however it also meet with the error floor phenomenon. We propose a scheme of utilizing unitary space-time symbol based serial concatenated convolutional code for multiple-antenna wireless communication systems over rapid fading...
Recently, a novel scheme employing unitary space-time symbol based turbo code (USTSBTC) has been proposed that can greatly reduce the system complexity while maintaining a fairly well performance compared with the bit wise processing version. However, as we know, an intrinsic pitfall of MAP decoding algorithm for turbo code is its too large amount storage requirement. We propose a sliding window for...
In this paper we evaluate the performance of a multi stage receiver for coded signals (using space time block codes) when MIMO (multi input multi output) channels are employed. This provides a new paradigm for transmission over Rayleigh fading channels where scattering phenomenon is a major obstruction. At the transmitter side data encoded using a space-time block code, and the encoded data is split...
