Abstract
The present invention relates to a system and method for the blind detection of BPSK signals in a multi-user environment. More particularly, the present invention provides a system and a method for blind detection of BPSK signals in an environment with multiple simultaneous transmitters. The received signal is a composite signal consisting of several delayed phase shifted and attenuated versions of the desired signal with other such signals from other transmitters. The present invention also provides a system for blind (without using training sequences) detection of BPSK signals in a multi-user environment. In particular, the system of the invention is of utility in the CDMA environment.
