Channel Polarization under Channel Noise with Memory
Tianfu Qi, Jun Wang
The channel polarization behavior of polar codes under noise with memory is investigated. By introducing a genie-aided channel model, we first show that the polarized subchannels s…

Polarization Decomposition and Its Applications
Tianfu Qi, Jun Wang
The polarization decomposition of arbitrary binary-input memoryless channels (BMCs) is studied in this work. By introducing the polarization factor (PF), defined in terms of the co…
