Patent ID: 6925258

Claim:
A system for increasing bandwidth efficiency of digital data communication links comprising; a space-time coder for error correction coding of input digital data into direct temporal and spatial data streams, said space-time coder applying trellis coding to reduce signal bandwidth while increasing data redundancy to compensate for errors through spatial and temporal channels; at least one signal source; at least one space-time modulator receiving and modulating the polarization states said at least one signal source with said spatial data from said direct temporal and spatial data streams received from said space-time coder; at least one amplifier for amplifying the output of said space-time modulator; one or more transmitters for transmitting the output signal from said at least one amplifier; one or more receivers for receiving and collecting the signal from said one or more transmitter; at least one space-time demodulator for direct temporal demodulation of amplitude, phase, and frequency and spatial demodulation of signal polarization of said signal from said one or more receivers; at least one low noise amplifier for amplifying a signal received from said at least one space-time demodulator to compensate for path loss; at least one space-time decoder for iterative decoding of direct temporal and spatial data streams received from said low noise amplifier; whereby bandwidth efficiency and throughput are increased.
