Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Full-rate, full-diversity space-time codes are consid- ered in the framework of asynchronous direct-sequence code- division multiple access with aperiodic random spreading se- quences. The system is described in a multiuser uplink channel with multiple transmit and receive antennas. Chip-level oversam- pling is used to exploit the cyclostationarity of multiple-access interference. A sphere decoder is employed to jointly decode the space-time codes and suppress the interference. Simulation is performed to show the validity of applying the sphere decoder to multiple-access interference suppression. The performance im- provement of the sphere decoder over the conventional minimum- mean-square-error detector is also studied.
