OFDM 传输的一种新的组合脉冲噪声缓解方案研究
摘要-Impulsive噪音缓解了正交频分复用(OFDM)可以使用两个阈值剪贴归零方案来完成。我们引入一个新的结合脉冲噪声消除方法,称为clippingreplacement-归零计划,其中有三个考虑阈值:限幅阈Tclip,更换门槛TREP和归零门槛Tnull。当接收到的OFDM样本的幅度高于TREP和下方Tnull我们将其设置为所述平均幅度JX?无噪声的OFDM样本第j。模拟结果表明,附加的动作,替换动作,与TREP的一个很好的选择带来在误码率的降低。

We investigate the case of independent Rayleigh faded paths between antenna elements and find that with
high probability extraordinary capacity is available. Compared to the baseline n = 1 case, which by Shannon’s
classical formula scales as one more bit/cycle for every 3 dB of signaltonoise
ratio (SNR) increase, remarkably
withMEAs, the scaling is almost like n more bits/cycle for each 3 dB increase in SNR. To illustrate how great this
capacity is, even for small n, take the cases n = 2, 4 and 16 at an average received SNR of 21 dB. For over 99
of the channels the capacity is about 7, 19 and 88 bits/cycle respectively, while if n = 1 there is only about 1.2
bit/cycle at the 99 level. For say a symbol rate equal to the channel bandwith, since it is the bits/symbol/dimension
that is relevant for signal constellations, these higher capacities are not unreasonable. The 19 bits/cycle for n = 4
amounts to 4.75 bits/symbol/dimension while 88 bits/cycle for n = 16 amounts t
