Accurate Performance Analysis of Coded Large-Scale Multiuser MIMO Systems with MMSE Receivers
In this paper, we estimate the uplink performance of large-scale multi-user multiple-input multiple-output (MIMO) networks. By applying minimum-mean-square-error (MMSE) detection, a novel statistical distribution of the signal-to-interference-plus-noise ...

Private Streaming With Convolutional Codes [PDF]
Recently, information-theoretic private information retrieval (PIR) from coded storage systems has gained a lot of attention, and a general star product PIR scheme was proposed. In this paper, the star product scheme is adopted, with appropriate modifications, to the case of private (e.g., video) streaming.

Generalized Weights of Convolutional Codes
In 1997 Rosenthal and York defined generalized Hamming weights for convolutional codes, by regarding a convolutional code as an infinite dimensional linear code endowed with the Hamming metric. In this paper, we propose a new definition of generalized weights of convolutional codes, that takes into account the underlying module structure of the code ...

Energy-Efficient Relay Aided Ad Hoc Networks Using Iteratively Detected Irregular Convolutional Coded, Unity-Rate Coded and Space-Time Trellis Coded Transceivers [PDF]
The nodes of ad hoc networks are typically batterypowered, hence requiring the employment of energy-efficient schemes. Near-capacity coding schemes allow a single link to communicate using the lowest possible transmit power, while achieving a low Frame ...

An efficient algorithm for the reconstruction of punctured convolutional codes
Puncturing is one of the methods of increasing the code rate, and the original code before puncturing is called the mother code. Any (N,K) convolutional code is obtainable by puncturing some (n,1) mother codes.
