MULTIPLE SUB-CARRIER SELECTION DIVERSITY ARCHITECTURE AND METHOD FOR WIRELESS OFDM

摘要

Sub-carrier selection methods and receiver architectures for receiving an Orthogonal Frequency Division Multiplexing band sensed by a plurality of antennas (10₁ - IO_N). Filtering (18) is applied to separately pass portions of the predetermined Orthogonal Division Multiplexing frequency band. Each separate portion encompasses one or more sub-bands of the predetermined Orthogonal Division Multiplexing frequency band. For each of the separate portions of the predetermined Orthogonal Division Multiplexing frequency band, the signal received from one of the plurality of antennas is selected. The selected signals for each separate portion are then combined in the time (analog) domain.
