A receiver may train its equalizer using consecutive pilot bursts, divide the traffic between the consecutive pilot bursts into multiple sub- segments, and interpolate the trained equalizer coefficients to obtain the coefficients for equalizing one or more of the sub-segments. The receiver may also determine signal to interference and noise ratio (SINR) values based on each of the consecutive pilot bursts, and interpolate the SINR for decoding one or more of the sub- segments. The receiver may be an access terminal receiver operating in a code division multiple access (CDMA) cellular system.

Un récepteur peut former son égaliseur à l'aide de rafales de signaux pilotes consécutifs, diviser le trafic entre les rafales de signaux pilotes consécutifs en plusieurs sous-segments, et interpoler les coefficients d'égaliseur formés pour obtenir les coefficients permettant d'égaliser un ou plusieurs des sous-segments. Le récepteur peut également déterminer un rapport signal sur interférence et bruit (SINR) d'après chacun des rafales de signaux pilotes consécutifs, et interpoler le SINR pour décoder un ou plusieurs des sous-segments. Le récepteur peut être un récepteur de terminal d'accès fonctionnant dans un système cellulaire d'accès multiple par répartition de code (CDMA).
