Interference cancellation technique for channel estimation in ofdm receivers

摘要

Receiver (RCV) adapted for determining an estimation of interferences when receiving an OFDM signal made of packets, each packet comprising a first training field (STF), a second training field (LTF), at least two header fields (SIG, HT-SIG, HT-STF, HT-LTF, VHTSIG1, VHTSIG2, VHTSTF,VHTLTF, VHTSIG) and data field, comprising- Means (MOD2) for detecting a first symbol value (D1) of a first header fields and a second symbol value (D2) of a second header field, said first and second header fields beholding to said at least two header fields and the modulation scheme being different between said first and second header fields;- Means (MOD3) for determining said estimation from said first (D1) and second (D2) symbol values.
