Transmit baseband filter and modulator for filtering and modulating a first bit rate signal into a Gaussian filtered modulated signal and a second transmit filter and modulator for filtering and modulating a second bit rate signal into a Quadrature Amplitude Modulated (QAM) signal. A first amplifier and first transmitter for nonlinearly amplifying and a second amplifier and second transmitter for linearly amplifying modulated signals. A diversity receiver and demodulator system for receiving and demodulating transmitted modulated signals. Processor, transmit baseband filter and modulator provides cross-correlated in-phase and quadrature-phase Gaussian filtered Gaussian Minimum Shift Keying (GMSK) modulated signal, spread spectrum Quadrature Phase Shift Keying (QPSK) modulated signal. Transmit processor and filter provides time division multiplexed (TDM) Gaussian filtered baseband signal and Orthogonal Frequency Division Multiplexed (OFDM) in-phase and quadrature-phase baseband modulated signal to a cellular network and to separate wireless network. Diversity receiver and demodulator provides demodulated cross-correlated in-phase and quadrature-phase filtered signal, with receive filter mis-matched to transmit filter.
