ABSTRACT:
Processors for processing, modulating, transmitting and receiving spread spectrum, CDMA, CSMA, OFDM, TDM, TDMA, filtered and cross-correlated signals. A first processor and filter for processing and filtering spread spectrum signals and a second processor for processing and filtering Time Division Multiplexed (TDM) or Time Division Multiple Access (TDMA) signals or for processing Orthogonal Frequency Division Multiplexed (OFDM) signals or a second processor for processing and shaping cross-correlated in-phase and quadrature-phase baseband signals and a selector for selecting and connecting either the first processor or the second processor processed signals to signal modulator and or transmitter. A first signal transmitter, for signal transmission in first Radio Frequency (RF) band and a second signal transmitter for signal transmission in second RF band of the processed signals.
