Apparatus and method for canceling interference in a single antenna 1xEV-DV mobile station |
摘要 |
A mobile station for canceling interference caused by a dominant interferer signal in a 1xEV-DV wireless network. The mobile station comprises an RF down-converter for outputting a down-converted signal, r(n); a first PN demodulator for multiplying the down-converted r(n) signal by a first PN code sequence to produce a first demodulated output signal; W Walsh code demodulators that multiply the first demodulated output signal by a selected set of W Walsh codes to produce W raw user signals; W subtractors that subtract a selected estimated interference signal from one of the W raw user signals to produce W estimated user signals; and a detector that outputs a detected user signal for each of the W estimated user signals that exceeds a first threshold value. The mobile station further comprises an interference estimator that receives W detected user signals from the first detector and outputs W estimated interference signals to the W subtractors.
