极化码(Polar Codes)是由Arikan于[1]中提出的、一种可以在二进制输入对称无记忆(Binary-Input Symmetric Memoryless)信道下达到信道容量的低复杂度前向纠错码。一经提出,便受到业内的密切关注和热烈讨论。而Arikan本人也受华为邀请参加了专属于他的颁奖仪式,可见该技术的重要性和开创性。 颁奖仪式www.bilibili.co...
Polarization Rate and Performance of Polar CodesIn this chapter, we will mathematically state the channel polarization theorem and prove it. In addition, the performance of polar codes will be mathematically analyzed.doi:10.1007/978-981-13-0737-9_5Orhan Gazi...

However, direct polar decoding of q-ary sources and channels is a difficult task. In this paper we introduce a likelihood ratio (LR) vector that can be expressed recursively for decoding q-ary polar codes defined via the basic polar transformation for finite fields of prime order, or via an...

This observation gives yet another justification as to why the polar transform yields capacity achieving and low complexity codes: the improvement in Etranslates to an improvement in complexity-error-probability trade-off. In analyzing polar codes, one examines auxiliary random processes that follow the...
HLCP(fx, fy; z) and HRCP(fx, fy; z) represent the transfer function for different polar- ization states. When calculating the hologram, all the light fields, spectra and transfer functions are discretely sampled with equal grids, and the Fourier transform and inverse transform of the ...
To define the Stokes parameters for linearly polarized radiation, we introduce two reference axes |$\boldsymbol {l}$| and |$\boldsymbol {r}$| so that |$\boldsymbol {l}$| lies in the meridian plane (plane defined by |$\boldsymbol {n}$| and the polar axis z) and |$\boldsymbol ...
