Short Packets over Block-Memoryless Fading Channels: Pilot-Assisted or Noncoherent Transmission?
Johan Östman, Giuseppe Durisi, Erik G. Ström +2
We present nonasymptotic upper and lower bounds on the maximum coding rate achievable when transmitting short packets over a Rician memoryless block-fading channel for a given requ…
Asymptotic Performance of Coded Slotted ALOHA with Multi Packet Reception
Cedomir Stefanovic, Enrico Paolini, Gianluigi Liva
In this letter, we develop a converse bound on the asymptotic load threshold of coded slotted ALOHA (CSA) schemes with K-multi packet reception capabilities at the receiver. Densit…
Ultra-Sparse Non-Binary LDPC Codes for Probabilistic Amplitude Shaping
Fabian Steiner, Gianluigi Liva, Georg Böcherer
This work shows how non-binary low-density parity-check codes over GF() can be combined with probabilistic amplitude shaping (PAS) (Böcherer, et al., 2015), which combines for…
Inactivation Decoding of LT and Raptor Codes: Analysis and Code Design
Francisco Lázaro, Gianluigi Liva, Gerhard Bauch
In this paper we analyze LT and Raptor codes under inactivation decoding. A first order analysis is introduced, which provides the expected number of inactivations for an LT code,…
Successive Cancellation Decoding of Single Parity-Check Product Codes
Mustafa Cemil Coşkun, Gianluigi Liva, Alexandre Graell i Amat +1
We introduce successive cancellation (SC) decoding of product codes (PCs) with single parity-check (SPC) component codes. Recursive formulas are derived, which resemble the SC deco…
Probabilistic Amplitude Shaping with Hard Decision Decoding and Staircase Codes
Alireza Sheikh, Alexandre Graell i Amat, Gianluigi Liva
We consider probabilistic amplitude shaping (PAS) as a means of increasing the spectral efficiency of fiber-optic communication systems. In contrast to previous works in the litera…
Short Codes with Mismatched Channel State Information: A Case Study
Gianluigi Liva, Giuseppe Durisi, Marco Chiani +2
The rising interest in applications requiring the transmission of small amounts of data has recently lead to the development of accurate performance bounds and of powerful channel…
Probabilistically-Shaped Coded Modulation with Hard Decision Decoding for Coherent Optical Systems
Alireza Sheikh, Alexandre Graell i Amat, Gianluigi Liva
We consider probabilistic shaping to maximize the achievable information rate of coded modulation (CM) with hard decision decoding. The proposed scheme using binary staircase codes…
Achievable Information Rates for Coded Modulation with Hard Decision Decoding for Coherent Fiber-Optic Systems
Alireza Sheikh, Alexandre Graell i Amat, Gianluigi Liva
We analyze the achievable information rates (AIRs) for coded modulation schemes with QAM constellations with both bit-wise and symbol-wise decoders, corresponding to the case where…
Physical-layer Network Coding: A Random Coding Error Exponent Perspective
Shakeel Salamat Ullah, Gianluigi Liva, Soung Chang Liew
In this work, we derive the random coding error exponent for the uplink phase of a two-way relay system where physical layer network coding (PNC) is employed. The error exponent is…
On the Error Probability of Short Concatenated Polar and Cyclic Codes with Interleaving
Giacomo Ricciutelli, Marco Baldi, Franco Chiaraluce +1
In this paper, the analysis of the performance of the concatenation of a short polar code with an outer binary linear block code is addressed from a distance spectrum viewpoint. Th…
