Abstract:
An interference cancellation technique is implemented in a receiver adapted for determining an estimation of interferences when receiving an OFDM signal made of packets. Each packet includes a first training field, a second training field, a first header field, a second header field and a data field. The receiver detects a first symbol value of the first header field, and a second symbol value of the second header field, the first and the second header fields having been modulated using different modulation schemes. The estimation of interferences is determined using the first and the second symbol values.
