Reducing phase errors on a communication device

摘要

A communication device that is configured for reducing phase errors is described. The communication device includes a processor and instructions stored in memory. The communication device calculates a sum channel in the frequency domain, estimates one or more impulse responses and isolates an impulse response for one or more wireless communication devices. The communication device also calculates a phase error for each wireless communication device and reduces the phase error for each wireless communication device.

1. A communication device that is configured for reducing phase errors, comprising:
a processor; memory in electronic communication with the processor; instructions stored in the memory, the instructions being executable to:
isolate an impulse response by separating the impulse response from a plurality of estimated impulse responses for each of a plurality of wireless communication devices;calculate a phase error for each wireless communication device by calculating an angle of a cross correlation of the isolated impulse response for the wireless communication device and an isolated impulse response for the wireless communication device of a first received symbol; andreduce the phase error for each wireless communication device based on the calculated error.
