摘要： A method and system are described for processing a received signal at a receiver in a communication system. The receiver includes a digital filter and automatic gain control means. Information indicating the frequency band of operation and the type of service of the received signal is received at the receiver from the communication system. The gain and filtering parameters of the receiver are set according to the received information. The received signal is processed at the receiver using the gain and filtering parameters. Optionally, a determination of whether the received signal contains adjacent channel interference above a predetermined allowable threshold may also be made and the determination may then be used in setting the gain and filtering parameters.

摘要： A sequence of received signals is identified, by a receiver of signals transmitted via a channel of a wireless communications system, as one of a number of known orthogonal sequences. The sequence of received signals is received (103); a modified sequence is calculated (105) by replacing some of the received signals by their complex conjugate values; the modified sequence is correlated (106) with each one of the number of known orthogonal sequences to obtain a correlation result for each of the known sequences; and the sequence of received signals is identified (107) as the known sequence having the largest correlation result. When some signals in the received sequence are complex conjugated before being correlated with the known sequences, the correlation sum will increase so that even in case of a considerable frequency error the correlation sum for the correct sequence will be sufficiently large to be distinguished from noise.

摘要： Receiver resources are allocated based on how subframes are allocated within in a frame between downlink and uplink transmissions and how often the receiver is expected to report feedback information associated with the downlink transmissions. Additional time is available for processing received data blocks if the feedback information derived from those blocks must be reported later than expected due to the unavailability of uplink subframes. According to one embodiment, received signals are processed by receiving transmission configuration information indicating how downlink and uplink subframes are allocated within a frame in the time domain. Based on the transmission configuration information, the receiver determines whether a delay that exceeds a feedback reporting interval assigned to the receiver will occur when reporting feedback information associated with the downlink subframes. Receiver resources are allocated based on whether a delay will occur when reporting the feedback information.
