摘要:
Adaptive reconfiguration of a wireless receiver is enabled based on channel geometry According to an embodiment, the wireless receiver includes a geometry factor processing module and signal processing modules, e.g. such as hut not limited to an SIR estimation module, a power estimation module, a despreading module, a low- pass filter, a combing weight generation module, a coefficient estimation module, a synchronization control channel interference canceller module, etc. The geometry factor processing module determines a geometry factor for the channel over which signals are transmitted to the wireless receiver, the geometry factor being a measure of the ratio of total transmitted power received by the wireless receiver to total interference plus noise power at the wireless receiver. One or more of the receiver signal, processing modules are reconfigurable based on the geometry factor.

This disclosure presents a receiver apparatus (10) and corresponding method that advantageously use ISI-canceling combining weights, as are generated for ISI suppression in the receiver's data signal combining operations, to suppress the effects of ISI from determinations of receiver frequency error. Such suppression yields more accurate receiver frequency error determination and, correspondingly, improved receiver frequency error compensation.

A method of selecting a transport format (11) for transmission of data blocks between a base station and a mobile terminal in a wireless telecommunications system, wherein the mobile terminal is capable of moving at a speed relative to the base station, comprises determining (101) transport formats (11) possible for transmission of data blocks from the device (1); and determining (102) for each possible transport format a set of quality metrics (12). The method further comprises determining (103) for each possible transport format modified sets of quality metrics (13, 14, 15, 18) in dependence of speed and code rate for different speeds; estimating (104) the speed of the mobile terminal, and selecting (105) one of said possible transport formats (11) for transmission of a data block in dependence of said estimated speed and said modified sets of quality metrics (13, 14, 15, 16). This provides a method of selecting a transport format (11) with improved performance in high speed conditions.
