Patent ID: 8437383

Claim:
A signal processing device within a distributed antenna system, the signal processing device comprising: a first radio frequency transceiver providing a first reception signal path, the first reception signal path having an uncompensated distortion function of G 1 (ω) with a first system response represented by y 1 (n), a first compensator coupled to the first reception signal path, the first compensator having a first filter H 1 (ω), the first filter H 1 (ω) having a first filter parameter vector {right arrow over (h)} 1 , wherein the first filter parameter vector {right arrow over (h)} 1 is determined from a first estimation of the first system response y 1 (n) of the first reception signal path; a second radio frequency transceiver providing a second reception signal path, the second reception signal path having an uncompensated distortion function of G 2 (ω) with a second system response represented by y 2 (n), a second compensator coupled to the second reception signal path, the second compensator having a second filter H 2 (ω), the second filter H 2 (ω), having a second filter parameter vector {right arrow over (h)} 2 , wherein the second filter parameter vector {right arrow over (h)} 2 is determined from a second estimation of the second system response y 2 (n) of the second reception signal path; wherein the first filter parameter vector {right arrow over (h)} 1 configures the first filter H 1 (ω) to produce a first output response that is a first delayed version of a first input to the first filter H 1 (ω); wherein the second filter parameter vector {right arrow over (h)} 2 configures the second filter H 2 (ω) to produce a second output response that is a second delayed version of a second input to the second filter H 2 (ω); and wherein the first radio frequency transceiver and the second radio frequency transceiver are coupled to a module that multiplexes uplink signals from the first radio frequency transceiver and the second radio frequency transceiver into a serial data stream.
