<p>A method of local maximum likelihood detection with bit extending and multiplexing to approach optimum performance as well as single-user performance in a high SNR regime in random densely and sparsely spread CDMA. The method is based on local maximum likelihood (''LML") detectors and bit extending and multiplexing, and can approach optimum performance of a GML detector as well as the single-user performance in the high SNR regime, while average per-bit complexity is liner in the number of detected bits and thus is suitable for implementation in practical CDMA systems.</p> |
