APPARATUS FOR SPREADING, SCRAMBLING AND CORRELATION IN A RECONFIGURABLE DIGITAL SIGNAL PROCESSOR

摘要

A hardware unit within a DSP includes various circuits and components that allow spreading, complex scrambling, and complex correlation to be performed at the software level in a programmable processor at the speed levels required by third generation wireless communication systems. Software level spreading and complex scrambling during transmitting and complex correlation during receiving are supported by the unit, resulting in higher performance and eliminates the need for ASICs.
