In this paper linear parallel interference cancellation (PIC) schemes are described and analysed using matrix algebra. It is shown that the linear PIC, whether conventional or weighted, can be seen as a linear matrix filter applied directly to the chip-matched filtered received signal vector. An expression for the exact bit error rate is obtained and conditions on the eigenvalues of the code correlation matrix and the weighting factors to ensure convergence are derived. The close relationship… CONTINUE READING
