In this paper, we propose an adaptive resource allocation algorithm to maximize the sum data rate for spatial division multiplexing access (SDMA) orthogonal division multiple access (OFDMA) systems using genetic algorithm. We perform zero forcing (ZF) beamforming at the transmitter constructing single and multiple beams for OFDMA systems with multiple transmit antennas. In order to reduce the complexity...
The paper deals with the realization on FPGA of a filter bank based multicarrier modem core. The main blocks of the modem core are for the transmitter: OQAM modulation for transmitter, synthesis filter bank composed from IFFT and polyphase network; and for the receiver: OQAM modulation for receiver, analysis filter bank composed from polyphase network and FFT. The modem core is implemented on FPGA...
