ABSTRACT:
Multiple-Input, Multiple-Output Orthogonal Frequency Division Multiplexing (“MIMO-OFDM”) modulation is described. An integrated circuit has blocks of memory of a fixed size. A physical layer block is configured for MIMO-OFDM. The physical layer block is a single MIMO-OFDM block for supporting transmitting via a plurality of antennas. The physical layer block includes buffers configured for storing sets of symbols at a time for transmitting via the plurality of antennas.
