Method and apparatus for transmission and reception of a signal over multiple frequencies with time offset encoding at each frequency

摘要

A method of processing a signal including the steps of: (a) modulating the signal using a modulator corresponding to a modulation, (b) sending the modulated signal over multiple frequencies where the signal is offset in time in each frequency, (c) receiving the signal over the multiple frequencies, (d) reconstructing the sent signal by reversing the time delay and combining the received signal from each frequency, and (e) demodulating the received combined signal using a demodulator corresponding to the modulation used in (a).

1. In a communication system having a single transmitting antenna and a single receiving antenna, a method of processing a signal, comprising the steps of:
(a) modulating the signal using a specified modulator and baseband frequency to form a modulated baseband signal; (b) converting the modulated baseband signal into multiple transmission frequencies; (c) delaying the modulated signal for each transmission frequency included in the multiple transmission frequencies by a time delay specific to said each transmission frequency; (d) combining said delayed modulated signals at said multiple transmission frequencies into a single combined signal for transmission; (e) sending the combined signal from said single transmitting antenna; (f) receiving the combined signal, where said receiving is done by said single receiving antenna; (g) reversing the time delay specific to said each transmission frequency; (h) converting said each transmission frequency to a respective baseband signal at the baseband frequency; and, (i) combining and demodulating the respective baseband signals using a demodulator corresponding to the modulation used in (a).
