Patent ID: 7817748

Claim:
An adaptive receiver, comprising: a buffer to store data samples from an incoming signal stream, wherein the signal stream is modulated using orthogonal frequency division multiplexing (OFDM), the buffer to store a number of OFDM data samples; a synchronization engine to perform signal recognition and characterization of the incoming signal stream, the characterization being according to a type of interference being received along with the incoming signal stream, the interference comprising co-channel interference caused by a device that is located remote to the adaptive receiver, the interference being at or above a threshold energy level, the characterization being either of a first type, a second type, or a third type, wherein: a signal stream of the first type comprises interference preceding the signal stream; a signal stream of the second type comprises interference occurring substantially after the signal stream is detected; and a signal stream of the third type comprises interference occurring substantially during the transmission of the signal stream; and a decoding engine to calculate a covariance matrix only after the signal stream is characterized as being the first type; wherein the adaptive receiver is operated as a maximum ratio combining receiver when the signal stream is of the second or third type or, alternatively, as a minimum mean square error receiver when the signal stream is of the first type.
