METHOD AND APPARATUS FOR SPUR CANCELLATION IN AN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING COMMUNICATION SYSTEM

摘要

A communication device (120) that is capable of operating in an OFDM communication system provides for cancellation of in-band spurs. The communication device identifies (308) a bin of multiple bins associated with an output of an inverse transformer and comprising a spur and estimates (310) one or more spur phase parameters and a spur amplitude in association with the identified bin. In one embodiment of the present invention, the one or more spur phase parameters includes a spur initial phase and a spur change rate. When the communication device receives (314) a signal from another communication device, the communication device transforms (316) the received signal to produce a multiple parallel output signals that are each associated with a bin of the multiple bins and cancels (318) a spur in an output signal associated with the identified bin based on the estimated one or more spur phase parameters and spur amplitude.
