Claim:
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).
