Cellular communications system with multicarrier signal processing

Claim 1

A wireless telecommunication system comprising: (1) a mobile switching center; (2) at least one base station that is operably connected to said mobile switching center and that is capable of receiving a multicarrier signal; (3) a multicarrier signal processor within said at least one base station, said multicarrier signal processor comprising: (i) a signal divider for creating at least a first signal, a second signal, and a third signal based on said multicarrier signal, and for putting said first signal onto a first signal path, said second signal onto a second signal path, and said third signal onto a third signal path; (ii) a signal combinet for receiving at least said first signal from said first signal path and a modified third signal from said third signal path, and for creating an output signal by injecting at least said modified third signal into said first signal in a feedforward architecture; (iii) an individual signal modifier in said third signal path for isolating from said third signal an isolated carrier signal, and for modifying a phase of said isolated carrier signal to create said modified third signal; and (iv) a controller for receiving said second signal from said second signal path, for analyzing said second signal to determine a relative power of each of a plurality of carrier signals which comprise said second signal, and for identifying said isolated carrier signal to be isolated by said individual signal modifier.

Claim 5

A method for processing a multicarrier signal, said method comprising: creating at least a first signal, a second signal, and a third signal based on said multicarrier signal; receiving said second signal in a controller; analyzing said second signal in said controller to identify at least one carrier signal; receiving said third signal in a signal modifier; isolating said at least one carrier signal from said third signal to create an isolated carrier signal; modifying a phase of said isolated carrier signal to create a modified carrier signal; and injecting said modified carrier signal into said first signal in accordance with a feedforward architecture.

Claim 6

A method for processing a multicarrier signal, said method comprising: creating at least a first signal, a second signal, and a third signal based on said multicarrier signal; receiving said second signal in a controller; analyzing said second signal in said controller to identify at least one carrier signal; receiving said third signal in a signal modifier; isolating said at least one carrier signal from said third signal to create an isolated carrier signal; modifying a phase of said isolated carrier signal to create a modified carrier signal; and injecting said modified carrier signal into said first signal in accordance with a feedforward architecture.
