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 )

随着蜂窝移动通信市场的巨大发展,下一代通信将是移动多媒体通信。这种情况产生了一个问题,如何对语音信源以外的多媒体信源进行功率控制。在探讨这个问题上,我们引入微观经济学中的数学模型和概念以及博弈论理论。在本文中,电话的通话质量被称为“效度”,对于一个CDMA电话通信的分布式功率控制被看作是一个‘非协作的博弈’。(CDMA mobile communication system is a technology which will be used in the next-generation communications system, so wideband CDMA technology has been unprecedented attention, and a large number of improved algorithm to improve the performance of CDMA system has emerged in its various research on key technologies.)
