Description: PEAK TO AVERAGE POWER RATIO REDUCTION OF DM
SIGNALS USING PEAK REDUCTION CARRIERS:
ABSTRACT
A technique is described for a better than 5 dB reduction
in the Peak to Average Power Ratio (PAPR) of an OFDM
signal. The optimal amplitude and phase of additional
peak reduction carriers (PRC) is obtained using a codebook,
which is obtained using a search of all possible
signal combinations.-PEAK TO AVERAGE POWER RATIO REDUCTION OF OFDM

正交分频多工:OFDM模拟器(外层函数)
create_channel:产生一个瑞利衰落信道复用,解的天线配置、正交分频多工结构、power-delay档案。
svd_decompose_channel:既然全网络知识是假设,在并行传输奇异值模式。这个函数分解这些频道模式。

-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 allocatio Platform: |
