Abstract:
A method of estimating an SINR ratio of an OFDM-CDMA transmission signal spread with spread codes, the transmission signal being transmitted between a transmission apparatus and a receiver apparatus, the method including: receiving the signal spread with spread codes at the receiver apparatus; and calculating, with a processor at the receiver apparatus, an estimate of the SINR ratio for the signal spread with the spread codes independently of a value of the spread codes.
