| titleOfInvention | Hybrid correlation and least squares channel estimation |
| abstract | A hybrid channel estimator for a wireless communication system receiver includes both correlation based and least squares based channel estimators. The correlation estimator is used when signal quality is low or noise is colored, The least squares estimator is used when signal quality is high or noise is white, Λn interference suppression filter improves signal quality by suppressing interference in a received signal. Generally, correlation channel estimation is performed initially, when signal quality is low and noise is colored, and interference suppression filtering is performed to increase signal quality by removing certain portion of interference and whitening the overall impairment spectrum. These may be done iteratively. When the signal quality improves, least squares channel estimation is performed, which may also be iterative. The training sequence and noise may be whitened prior to performing least squares channel estimation, which is the final operation before channel estimates are forwarded to a demodulator. |
