Design and Analysis of Index codes for 3-Group NOMA in Vehicular Adhoc Networks
Sai Pavan Deekshitula, B. Sundar Rajan
Index coding (IC) is a source coding technique employed to improve spectral utilisation, where the source node aims to satisfy users' demands by making minimum transmissions. Non-o…
Maximum Likelihood Decoder for Index Coded PSK Modulation for Priority Ordered Receivers
Divya U. S., B. Sundar Rajan
Index coded PSK modulation over an AWGN broadcast channel, for a given index coding problem (ICP) is studied. For a chosen index code and an arbitrary mapping (of broadcast vectors…
A Novel MCMC Based Receiver for Large-Scale Uplink Multiuser MIMO Systems
Tanumay Datta, N. Ashok Kumar, A. Chockalingam +1
In this paper, we propose low complexity algorithms based on Markov chain Monte Carlo (MCMC) technique for signal detection and channel estimation on the uplink in large scale mult…
Secrecy Capacity of the Gaussian Wire-Tap Channel with Finite Complex Constellation Input
G. D. Raghava, B. Sundar Rajan
The secrecy capacity of a discrete memoryless Gaussian Wire-Tap Channel when the input is from a finite complex constellation is studied. It is shown that the secrecy capacity curv…
A Hybrid RTS-BP Algorithm for Improved Detection of Large-MIMO M-QAM Signals
Tanumay Datta, N. Srinidhi, A. Chockalingam +1
Low-complexity near-optimal detection of large-MIMO signals has attracted recent research. Recently, we proposed a local neighborhood search algorithm, namely `reactive tabu search…
Near-ML Signal Detection in Large-Dimension Linear Vector Channels Using Reactive Tabu Search
N. Srinidhi, Saif K. Mohammed, A. Chockalingam +1
Low-complexity near-optimal signal detection in large dimensional communication systems is a challenge. In this paper, we present a reactive tabu search (RTS) algorithm, a heuristi…
