摘要： A scheme determines the first significant path (FSP) of a received multipath signal, from data defining the relative delay and the amplitude of the individual signal paths occurring in a series of time frames. The scheme includes filtering the data to spread the signal paths, performing a persistence test between frames to reject spurious signal paths, combining the energy of the signal paths in a frame, applying a test to determine the time at which the combined energy satisfies a criterion, and selecting the FSP dependent on that time. The combined energy may be evaluated within a sliding window, and the position of the window within the frame determined that maximizes the combined energy. Alternatively, the combined energy may be evaluated as the cumulative energy through the frame, and the position determined at which the cumulative energy reaches a threshold.

摘要： In a receiver of a UMTS telecommunication system a process for performing the Outer Loop power control in a User Equipment is provided. The receiver includes an improved outer loop power control mechanism that estimates a Signal to Interference target (SIRtarg) based on a Block Error Rate target (BLERtarg) received from a base station. The outer loop control mechanism estimates a BLER value (BLERest) based on a number of received blocks and then adjusts a SIR target value (SIRtarg) based on the relationship between BLERtarg and BLERest. Meanwhile, simultaneously in parallel, the outer loop power control mechanism monitors for a potential convergence of a first SIR value with the SIRtarg and upon detection of such potential convergence applying a correction to SIRtarg.

摘要： A wireless communication system includes a primary station which has a transmitter for transmitting wireless signals on a downlink, and a plurality of secondary stations each having a receiver for receiving signals on the downlink and a transmitter for transmitting on an uplink. In a normal, loaded condition a synchronization channel and a data channel are present on the downlink and closed power control is achieved by measuring the signal to interference ratio (SIR) in a received downlink transmission, comparing the measured SIR with a target SIR and sending a power adjust indication on the uplink to cause the primary station to adjust its transmitted power on the downlink. The secondary station monitors the downlink and, in response to detecting an unloaded cell condition, determines a target SIR offset which it applies to the target SIR to overcome interference from the presence of the synchronization channel on the downlink.

摘要： A method for tuning an oscillator frequency produced in a radio-receiver chain is based on a slope analysis of a residual difference between the oscillator frequency and a carrier frequency of a radio-received signal. Depending on the slope value calculated, a bandwidth of a low-pass time-filtering that is effective for the frequency difference is increased or set back to a default value. The method provides an improved trade-off between tuning precision and dynamic behavior when the frequency difference drifts rapidly.
