Satellite receiver with interfering signal cancellation
First Claim
1. A method for communication, comprising:
- receiving a Radio Frequency (RF) channel containing a desired signal conforming to a first air interface and an interfering signal conforming to a second air interface;
synchronizing a first receiver that is configured for the first air interface and a second receiver that is configured for the second air interface to a common frequency and timing reference; and
while the first and second receivers are synchronized, decoding the desired signal from the RF channel using the first receiver to generate a first output, decoding the interfering signal from the RF channel using the second receiver to generate a second output, and reconstructing the desired signal while suppressing the interfering signal by jointly processing the first and second outputs.

Abstract
A method for communication includes receiving a Radio Frequency (RF) channel containing a desired signal conforming to a first air interface and an interfering signal conforming to a second air interface. A first receiver configured for the first air interface and a second receiver configured for the second air interface are synchronized to a common frequency and timing reference. While the first and second receivers are synchronized, the desired signal is decoded from the RF channel using the first receiver to generate a first output, the interfering signal is decoded from the RF channel using the second receiver to generate a second output, and the desired signal is reconstructed while suppressing the interfering signal by jointly processing the first and second outputs.

13. A communication apparatus, comprising:
-
a front end, which is configured to receive a Radio Frequency (RF) channel containing a desired signal conforming to a first air interface and an interfering signal conforming to a second air interface; a first receiver, which is configured to reconstruct the desired signal from the RF channel by decoding the first air interface, to produce a first output; a second receiver, which is configured to reconstruct the interfering signal from the RF channel by decoding the second air interface, to produce a second output; a reference unit, which is configured to synchronize the first and second receivers to a common frequency and timing reference; and an interference regeneration unit, which is configured to provide the second output to the first receiver, and to cause the first receiver to reconstruct the desired signal while suppressing the interfering signal. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
