On the use of PN Ranging with High-rate Spectrally-efficient Modulations
Barbara Ripani, Andrea Modenini, Roberto Garello +2
In this paper, we study the feasibility of coupling the PN ranging with filtered high-order modulations, and investigate the simultaneous demodulation of a high-rate telemetry stre…
Code Design for Non-Coherent Detection of Frame Headers in Precoded Satellite Systems
Farbod Kayhan, Guido Montorsi
In this paper we propose a simple method for generating short-length rate-compatible codes over that are robust to non-coherent detection for -PSK constellations.…
User Clustering for Multicast Precoding in Multi-Beam Satellite Systems
Alessandro Guidotti, Alessandro Vanelli-Coralli, Giorgio Taricco +1
Current State-of-the-Art High Throughput Satellite systems provide wide-area connectivity through multi-beam architectures. However, due to the tremendous system throughput require…
Low Complexity Two-Stage Soft/Hard Decoders
Guido Montorsi, Farbod Kayhan
Next generation wireless systems will need higher spectral efficiency as the expected traffic volumes per unit bandwidth and dimension will inevitably grow. As a consequence, it is…
Challenges and some new directions in channel coding
Erdal Arikan, Najeeb ul Hassan, Michael Lentmaier +2
Three areas of ongoing research in channel coding are surveyed, and recent developments are presented in each area: spatially coupled Low-Density Parity-Check (LDPC) codes, non-bin…
Capacity bounds for MIMO microwave backhaul links affected by phase noise
Giuseppe Durisi, Alberto Tarable, Christian Camarda +2
We present bounds and a closed-form high-SNR expression for the capacity of multiple-antenna systems affected by Wiener phase noise. Our results are developed for the scenario wher…
Constellation Design for Transmission over Nonlinear Satellite Channels
Farbod Kayhan, Guido Montorsi
In this paper we use a variation of simulated annealing algorithm for optimizing two-dimensional constellations with 32 signals. The main objective is to maximize the symmetric pra…
Constellation Design for Channels Affected by Phase Noise
Farbod Kayhan, Guido Montorsi
In this paper we optimize constellation sets to be used for channels affected by phase noise. The main objective is to maximize the achievable mutual information of the constellati…
Capacity-achieving CPM schemes
Alberto Perotti, Alberto Tarable, Sergio Benedetto +1
The pragmatic approach to coded continuous-phase modulation (CPM) is proposed as a capacity-achieving low-complexity alternative to the serially-concatenated CPM (SC-CPM) coding sc…
Encoding for the Blackwell Channel with Reinforced Belief Propagation
A. Braunstein, F. Kayhan, G. Montorsi +1
A key idea in coding for the broadcast channel (BC) is binning, in which the transmitter encode information by selecting a codeword from an appropriate bin (the messages are thus t…
Design and Performance Analysis of a New Class of Rate Compatible Serial Concatenated Convolutional Codes
Alexandre Graell i Amat, Guido Montorsi, Francesca Vatta
In this paper, we provide a performance analysis of a new class of serial concatenated convolutional codes (SCCC) where the inner encoder can be punctured beyond the unitary rate.…
