A novel RLS space-time receiver in multi-path CDMA channels
Licheng Jiao · Journal of China Institute of Communications · 2003
We first present a novel recursive least-square (RLS) algorithm for quadratic programming based on linear constraint that appears multiuser detection in multipath CDMA channels. This method can completely avoid the matrix inversion introduced into by constraints (which relative to the normal RLS). By combining this algorithm and CDMA multiuser system, we present a novel adaptive receiver. The results of the simulations illustrate that this method is valid for the performance of detection and convergence.
