Abstract:
1. An apparatus for wireless communication in a power-limited, very wideband system, the apparatus comprising: a wireless communication device having a media access controller (MAC) and a physical layer (PHY) that are adapted for a multiple-input-multiple-output (MIMO) orthogonal frequency-division multiple access (OFDMA) communication scheme in a power-limited wideband system; a plurality of antennas, operationally coupled to said device, to send and receive wireless communication signals according to said MIMO-OFDMA communication scheme; and a resource allocator, to allocate transmission resources of said device into desired MIMO channels optimized according to at least one of signal-to-noise ratio (SNR), bandwidth, number of users, and signal-to-noise-plus-interference ratio (SINR), wherein said desired MIMO channels are optimized according to SNR, to include low rank MIMO channels at low SNR and to include high rank MIMO channels at high SNR.
