Coded noncoherent communication with amplitude/phase modulation: from shannon theory to practical architectures

Noncoherent Amplitude/Phase Modulated Transmission Schemes for Rayleigh Block Fading Channels

“…At the receiver, not only the iterative noncoherent detection and decoding algorithm between the channel decoder and the detector is executed, but also the extrinsic information is exchanged between adjacent codewords. 4) Compared to the scheme described in [15], the constructed noncoherent coded schemes are capable of providing a significant improvement, either in the error-floor or the waterfall region. The rest of this paper is organized as follows: Section II provides the PEP analysis for the uncoded schemes using APM signals.…”

“…In [15], the authors further modified the scheme developed in [14] in order to apply them to high-order APM signals. The overall detection process presented in [15] considers both a low complexity and a reasonable level of reliability, and is divided into two steps: the amplitude estimation for the channel coefficient, and the detection based on the phase quantization of the channel coefficient.…”

In this paper, for APM signals, the PEP when using the ML detector is derived, and the associated coded schemes are investigated, where the channel model considered is the noncoherent Rayleigh block fading channel with coherence interval T .…”

Non-coherent UWB receiver for multi-level spectrally-encoded spread-time CDMA systems

“…Inspired by low-complexity implementation, communication schemes that are suitable for non-coherent reception are considered in the IEEE 802.15.4a standard [9]. There are some popular non-coherent UWB receiver structures for which the performance was investigated in the [10][11][12][13] literature. In this paper we will design and investigate the performance of an SE/ST UWB non-coherent system in the presence of multiple users.…”
