Method for eliminating interference in an ofdm radio receiver
Abstract
The invention relates to a eliminating OFDM (Orthogonal Frequency Division Multiplexing) in a wireless receiver interference method. The method, received part coded signals on the top subcarrier, and reliable information with of the signals is provided with them and soft decoding. To the invention, and subcarrier the signal connected to the ratio of greater inequality as reliable information, received signal amplitude with multiple interference amplitude to determine the meaconing ratio. By calculating group of the signals' amplitude deviates the signal group deviation the middle of amplitude layer to determine the amplitude interference. The middle amplitude layer of the signal group of the averaging values, the middle or multiple statistics; the sizes of express the signal group the middle layer of amplitude. Deviates signal group deviation the middle of amplitude layer is the standard deviation and when of the signal wire or multiple other expresses offset statistic. The signal units amplitude the continuous element and time domain and/or from the frequency domain in the adjacent subcarrier designated. The invention also relates to a method and a OFDM wireless receiver.
