Voice over Internet Protocol (VoIP) voice signal processed into Orthogonal Frequency Division Multiplexed (OFDM) or Orthogonal Frequency Division Multiple Access (OFDMA) signal. Processor and transmit filter for processing and filtering a signal and for providing a Time Division Multiple Access (TDMA) signal. Processing and filtering a signal and providing cross-correlated in-phase and quadrature-phase filtered baseband signal. Modulator and a transmitter for modulation and transmission of selected or combined signal. A two antenna receiver for receiving transmitted signal, a demodulator, receiver 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 filter for filtering of the TDMA signal and receive processor for processing provides processed received baseband mis-match filtered cross-correlated in-phase and quadrature-phase TDMA signal. Processor and transmit baseband filter for processing and filtering a signal and for providing cross-correlated in-phase and quadrature-phase filtered baseband signal including a location finder signal. VoIP multimode Wireless Local Area Network (WLAN), wireless fidelity (Wi-Fi), Global Mobile System (GSM) cellular network, spread spectrum and CDMA systems. Transmitter operated as a linearly amplified or linearized amplifier transmitter and a second transmitter operated as a Non-Linearly Amplified (NLA) transmitter.
