US 8,411,725 B2 · Channel geometry detector

Abstract

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 but 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.

Dependent claims

A method of re-configuring a wireless receiver, comprising:

computing a first signal-to-interference ratio (SIR) value when the wireless receiver is configured as a maximum ratio combining receiver and a second SIR value when the wireless receiver is configured as an equalizing receiver;
determining a geometry factor for a channel over which signals are transmitted to the wireless receiver, the geometry factor being a measure of a ratio of total transmitted power received by the wireless receiver to total interference plus noise power at the wireless receiver, and the geometry factor is based on a ratio of the first and second SIR values;
and
reconfiguring one or more signal processing modules of the wireless receiver based on the geometry factor.
