Abstract:
A modem for communicating data through a channel, said modem comprising:a modulator interfaced to a transmission means, said modulator further comprising at least two distinct modulation schemes; a signal processor interfaced to a receiving means, said signal processor further comprising at least two distinct demodulation schemes, each of said at least two distinct demodulation schemes corresponding to said at least two distinct modulation schemes; said at least two modulation schemes further comprise one of at least two modulation techniques and one of at least one encoder; said at least two demodulation schemes further comprise one of at least two demodulation techniques and one of at least one decoder, said at least two demodulation techniques corresponding to said at least two modulation techniques, and said at least one decoder corresponding to said at least one encoder; said modulator is operable to produce a channel probe signal; an intelligence module, said intelligence module further comprising a modulator interface to transfer data between said intelligence module and said modulator, said transferred data comprising a modulation code to select one of said at least two distinct modulation schemes; a signal processor interface to transfer data between said intelligence module and said signal processor; a modulator control module to accept data from said modulator, transfer data to said modulator, and control said modulator; a signal processor control module to accept data from said signal processor, transfer data to said signal processor, and control said signal processor; and a channel estimation module.
