Abstract
Mottaker, eller en integrert krets (IC) inkorporert i denne, som omfatter en hurtigfouriertransfomasjons (FFT)-basert (eller en hybrid FFT-basert) glidevindus blokklineær utjevner (BLE) for generering av utjevnede sampler. Denne BLE omfatter en støynivåestimerer, første og andre kanalestimerere, en FFT-basert chip-nivå-utjevner (CLEQ) og en kanalovervåkningsenhet. Støynivåestimereren vil generere et støynivåestimat basert på to forskjellige samplingsdatastrømmer. Kanalestimererene vil generere respektive kanalestimater basert på samplingsdatastrømmene. Kanalovervåkningsenheten vil generere et første kanalovervåkningssignal omfattende trunkerte kanalestimatvektorer basert på kanalestimatene, og et andre kanalovervåkningssignal som vil angi en tilnærmet endringsrate for de trunkerte kanalestimatvektorer. Den FFT-baserte CLEQ vil generere de utjevnede sampler basert på støynivåestimatet, én-blokksampler av de første og andre samplingsdatastrømmer, kanalestimatene og overvåkningssignalene.
