RAKE RECEIVER WITH MULTI-PATH INTERFERENCE ACCOMMODATION

摘要

A method of extracting data from a received signal including multi-path interference in a rake receiver. The method includes sampling and filtering the received signal; estimating a time delay (a) between paths for the filtered samples psi(tau); and estimating channel complex coefficient (b) for the filtered samples psi(tau). Transmitted data x(tau1) is extracted from the filtered samples psi(tau) for each path l by solutions of simultaneous equations of the following filtered samples psi(tau) equation (Formula I) wherein k is a particular path, Np is the number of visible paths, (c) is a a double convolution matrix of the filtering process and (d) is the pseudo inverse, Ass (taul) is the product of spreading and scrambling matrices and (e) is the inverse, and (f) is noise.
