| 20080212666 | Interference rejection in radio receiver - An interference rejection algorithm for a radio receiver is presented. According to the present solution a signal comprising a training sequence and a data sequence is received at the radio receiver. A radio channel response may be estimated from the received training sequence, and interference parameters may be estimated from at least one of the received training sequence and the received data sequence, the estimation of the interference parameters comprising smoothing a frequency spectrum of at least one of the estimated channel response and the estimated interference parameters through averaging. Then, frequency domain interference suppression weights are calculated from the estimated channel response and the interference parameters, and weighting of the received data sequence is carried out with the calculated weights. | 09-04-2008 |
| 20080240311 | Frequency offset correction - A frequency error correction scheme applicable in a receiver of a mobile telecommunication system is presented. The present frequency error correction scheme is carried out in a time domain after an equalization process. The present frequency error correction scheme may be applied to a base station receiving signals transmitted according to a single-carrier frequency division multiple access communication scheme. The separation of different received signals for further processing is carried out in the frequency domain before the equalization and the frequency error correction. | 10-02-2008 |
| 20090202031 | Delay estimation for a timing advance loop - An apparatus includes a radio frequency receiver and a timing adjustment unit that contains at least two channel impulse response estimators. The at least two channel impulse response estimators include an on-time estimator and at least one of an early estimator and a late estimator. The apparatus also includes a calculation unit that is configurable to obtain a channel estimate for each measured channel impulse response and to average obtained channel estimates over a plurality of received signal events to determine a timing adjustment in accordance with residual signal power. | 08-13-2009 |
