Abstract

Voice and location finder Analog to digital (A/D) converted signal is processed and provided to Orthogonal Frequency Division Multiplexed (OFDM), Orthogonal Frequency Division Multiple Access (OFDMA), Time Division Multiple Access (TDMA), Global Mobile System (GSM), spread spectrum and Wideband Code Division Multiple Access (WCDMA) baseband processor, filter, modulation format selectable modulator and transmitter. Receiver and modulation format selectable demodulator for location finder satellite and ground based location finder, Wireless Local Area Network (WLAN), wireless fidelity (Wi-Fi), world wide web (www) and cellular network provided signals. Modulator and a transmitter for modulation and transmission of selected or combined signal having two distinct transmitters operated in separate radio frequency (RF) bands. Receiver with two antennas for receiving transmitted signal, a demodulator, receive filter and receiver processor for demodulation, filtering and processing of received TDMA signal. Receive filter for filtering of the TDMA signal is mismatched to the transmit TDMA baseband filter. Receive processor provides received baseband mis-match filtered cross-correlated in-phase and quadrature-phase TDMA signal.
