Abstract

A modulator for a multimode wireless transmitter is provided. In general, the modulator has three modes of operation: an Enhanced Data Rates for Global System for Mobile Communications Evolution (EDGE) mode, which may be referred to as an 8-Level Phase Shift Keying (8PSK) mode; a Gaussian Minimum Shift Keying (GMSK) mode; and a Wideband Code Division Multiple Access (WCDMA) mode.
