OFDM—MIMO系统的matlab程序
MIMO OFDM Simulator:
OFDM.m: OFDM Simulator (outer function)
create_channel.m: Generates a Rayleigh fading frequency-selective channel, parametrized by the antenna configuration, the OFDM configuration, and the power-delay profile.
svd_decompose_channel.m: Since full channel knowledge is assumed, transmission is across parallel singular value modes. This function decomposes the channel into these modes.
BitLoad.m: Apply the bit-loading algorithm to achieve the desired bit and energy allocation for the current channel instance.
ComputeSNR.m: Given the subcarrier gains, this simple function generates the SNR values of each channel (each singular value on each tone is a separate channel).
chow_algo.m: Apply Chow's algorithm to generate a particular bit and energy allocation.
EnergyTableInit.m: Given the SNR values, form a table of energy increments for each channel.
campello_algo.m: Apply Campello's algorithm to converge to the optimal bit and energy allocation for the given channel conditions.
ResolvetheLastBit.m: An optimal bit-loading of the last bit requires a unique optimization.
modulate.m: Modulate the random input sequence according to the bit allocations for each channel.
ENC2.mat: BPSK Modulator
ENC4.mat: 4-QAM Modulator (Gray coded)
ENC16.mat: 16-QAM Modulator (Gray coded)
ENC64.mat: 64-QAM Modulator (Gray coded)
ENC256.mat: 256-QAM Modulator (Gray coded)
precode.m: Precode the transmitted vector at each time instance by filtering the modulated vector with the right-inverse of the channel's right singluar matrix.
ifft_cp_tx_blk.m: IFFT block of the OFDM system.
channel.m: Apply the channel to the OFDM frame.
fft_cp_rx_blk.m: FFT block of the OFDM system.
shape.m: Complete the diagonalization of the channel by filtering the received vector with the left-inverse of the channel's left singular matrix.
demodulate.m: Perform a nearest neighbor search knowing the transmit constellation used.
