Patent ID: 7158494

Claim:
A method of multi-mode RF communications, comprising: during a first timeslot, transmitting a first communications signal in accordance with one of a first communications standard using constant envelope modulation and a second communications standard using varying-envelope modulation; ramping down the first communications signal at the end of the first timeslot; and during a second adjacent timeslot, ramping up a second communications signal and transmitting the same in accordance with a different one of said first communications standard and said second communications standard; independently setting a power level of the communications signal in the first and second timeslots; if the first communications signal is not a constant-envelope signal having only a phase component, converting the first communications signal to obtain a phase component thereof and a magnitude component thereof; and if the second communications signal is not a constant-envelope signal having only a phase component, converting the second communications signal to obtain a phase component thereof and a magnitude component thereof.
