Abstract
Polar and quadrature modulator for receiving a baseband processed voice signal and for processing, modulating and transmitting voice signal. Voice signal processor and modulator for processing voice signal into Orthogonal Frequency Division Multiplexed (OFDM) or Orthogonal Frequency Division Multiple Access (OFDMA) signal. A location finding signal receiver, demodulator and processor for receiving, demodulating and processing a location finder signal into demodulated processed location finder signal. Location finder signal receiver receiving signal from two or more satellite and two or more ground based transmitters. Diversity receivers for signal reception from cellular and from Wireless Local Area Network (WLAN). Filtered polar modulated signal used in a Time Division Multiple Access (TDMA) system including Global Mobile System (GSM). Receiver for receiving transmitted signal has a radio frequency (RF) unit which is located at a remote location from demodulator.
