Title: DEMODULATOR CIRCUIT FOR DEMAPPING A MULTI-CARRIER SIGNAL USING CHANNEL STATE INFORMATION
Abstract:
The invention relates to a demodulator circuit in a communication system using a multi-carrier modulation scheme. The demodulator makes efficient use of channel state information for respective carriers in the multi-carrier modulation to de-map the received data. An efficient method of calculating channel state information is also disclosed.
