This article will discuss the many available modulation technology options that are used for various EDGE systems, including direct-launch conversion transmitter (DCT), small-signal polar modulation (sometimes called “polar lite”), and large-signal open polar modulation, and compare them to the more effective, large-signal closed polar loop solution that delivers the best overall system perform...

We consider the joint design of polar coding and higher-order modulation schemes for ever increased spectral efficiency. The close connection between the polar code construction and the multi-level coding approach is described in detail. Relations between different modulation schemes such as bit-interleaved coded modulation (BICM) and multi-level coding (MLC) in case of polar-coded modulation a...

Polar coded grayscale image communication over additive white Gaussian noise (AWGN) channels using orthogonal frequency division multiplexing (OFDM) system is demonstrated in this paper. The OFDM technique is effective multicarrier technique used in the high-speed transmission system. Polar codes are recently applied to the binary memoryless channel and binary erasure channels for achieving nea...

A framework is proposed that allows for a joint description and optimization of both binary polar coding and 2 -ary digital pulse-amplitude modulation (PAM) schemes such as multilevel coding (MLC) and bit-interleaved coded modulation (BICM). The conceptual equivalence of polar coding and multilevel coding is pointed out in detail. Based on a novel characterization of the channel polarization ph...

In this paper, density evolution-based construction methods to design good polar codes on impulsive noise channels for single-carrier and multi-carrier systems are proposed and evaluated. For a single-carrier system, the tight bound of the block error probability (BLEP) is derived by applying density evolution and the performance of the proposed construction methods are compared. For the multi-...

In this paper, we apply polar codes to a modified version of OFDM systems with index modulation which is called in-phase/quadrature (OFDM-I/Q-IM). We provide general design guidelines for the proposed polar-coded OFDM-I/Q-IM systems. system, at transmitter, employ random frozen bits appending scheme not only makes code compatible but also improves bit error rate (BER) performance system. Furthe...

The polar codes are proven to be capacity-achieving and are shown to have equivalent or even better finite-length performance than the turbo/LDPC codes under some improved decoding algorithms over the additive white Gaussian noise (AWGN) channels. Polar coding is based on the so-called channel polarization phenomenon induced by a transform over the underlying binary-input channel. The channel p...

We propose the progressive rate-filling method as a framework to study agile construction of multilevel polar-coded modulation. show that bit indices within each component polar code can follow fixed, precomputed ranking sequence (e.g., Polar in 5G standard) while their allocated rates (i.e., number information bits code) be fast computed by exploiting target sum-rate approximation and proper m...
