Cutoff Rate Bounds and Constellation Shaping under Mixed Gaussian-Impulsive Noise
Tianfu Qi, Jun Wang
Mixed noise, composed of white Gaussian noise (WGN) and impulsive noise (IN), appears in numerous communication scenarios and can severely degrade system performance. In this paper…

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…
