Modulation and coding for quantized channels [PDF]
, 2007 We investigate reliable communication over quantized channels from an information theoretical point of view. People seldom consider the effect of quantization in conventional coded modulation systems since Analog-to-Digital (AD) converters used in these ...

Peak-to-average power ratio of good codes for Gaussian channel [PDF]
, 2014 Consider a problem of forward error-correction for the additive white Gaussian noise (AWGN) channel. For finite blocklength codes the backoff from the channel capacity is inversely proportional to the square root of the blocklength.

Performance Analysis of CA‐Polar Code for 5G‐IoT Low Power Wide Area Networks
Internet Technology Letters, Volume 9, Issue 2, March/April 2026.ABSTRACT CRC‐Aided Polar (CA‐Polar) codes are the standardized channel coding scheme for control channels of 5G eMBB service class due to their capacity achieving performance. This work aims to assess the compatibility and scalability of CA‐Polar codes toward low power IoT applications coming under the domain of LPWAN.

Probabilistic Shaping for the AWGN Channel
, 2023 In this report, we study communication over an additive white Gaussian noise channel with a fixed signal constellation. We measure how much information we can send through this channel and how to improve the rate of communication by changing the input probability distribution.

Concatenated Coding for the AWGN Channel With Noisy Feedback [PDF]
IEEE Transactions on Information Theory, 2011 The use of open-loop coding can be easily extended to a closed-loop concatenated code if the channel has access to feedback. This can be done by introducing a feedback transmission scheme as an inner code. In this paper, this process is investigated for the case when a linear feedback scheme is implemented as an inner code and, in particular, over an ...

TranQuiL: Long Range Detection and Localization of Interference in Radio Quiet Zones
Radio Science, Volume 61, Issue 1, January 2026.Abstract Radio Quiet Zones (RQZs) have been established to prevent radio sources from causing harmful interference to sensitive radio telescopes, which study extremely faint cosmic radio waves. Even with strict regulations, such interference is growing due to the widespread use of consumer electronics, emitting in many different frequency bands ...
