摘要: An arrangement and method in a communication system such as an Orthogonal Frequency Division Multiplexing (OFDM) radio receiver for reducing the impact of interference from an intermittent interfering signal transmitted by an interfering system which may be co-located with the OFDM system or may be remotely located. Each OFDM symbol in a received OFDM signal includes a guard interval (GI), a middle portion, and a last portion identical to the GI. The arrangement determines which portion of each OFDM symbol is contemporaneous with the interfering signal and time-shifts a fast Fourier transform (FFT) window in the OFDM receiver to minimize or eliminate FFT processing of samples of the OFDM symbol that are contemporaneous with the interfering signal, thereby minimizing the impact of the interfering signal.

摘要: A system and method for correlating communication sessions. A globally unique correlation identifier is created and exchanged between the parties during SIP session setup to allow for association and correlation of additional SIP sessions. The correlation information may then be used by network and session entities to perform different services.
