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…

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…
