Patent ID: 7545883

Claim:
A system comprising: a processor, filter, first and second modulator for processing and filtering a first bit rate signal into time division multiplexed (TDM) filtered signal and a second bit rate signal into Orthogonal Frequency Division Multiplexed (OFDM) signal and for providing processed TDM filtered signal to first modulator and processed OFDM signal to second modulator for modulation and transmission of the modulated signal; a transmission system comprising two distinct transmitters for transmission of the modulated signal, wherein said distinct transmitters comprise a first amplifier operated in a linear or a linearized mode and a second amplifier operated in a nonlinear or saturated mode; a receiver system comprising two receivers for receiving a Radio Frequency (RF) signal and for providing received RF signal to a demodulator system for demodulation of received signal; and a demodulator system comprising a demodulator, filter and processor for demodulation, filtering and processing received signal.
