Iterative Matrix Inversion Based Low Complexity Detection in Large/Massive MIMO Systems
Vipul Gupta, Abhay Kumar Sah, A. K. Chaturvedi
Linear detectors such as zero forcing (ZF) or minimum mean square error (MMSE) are imperative for large/massive MIMO systems for both the downlink and uplink scenarios. However the…
Conditional Entropy based User Selection for Multiuser MIMO Systems
Gaurav Gupta, A. K. Chaturvedi
We consider the problem of user subset selection for maximizing the sum rate of downlink multi-user MIMO systems. The brute-force search for the optimal user set becomes impractica…
User Selection in MIMO Interfering Broadcast Channels
Gaurav Gupta, Ajit K Chaturvedi
Interference alignment aims to achieve maximum degrees of freedom in an interference system. For achieving Interference alignment in interfering broadcast systems a closed-form sol…
Construction of Turbo Code Interleavers from 3-Regular Hamiltonian Graphs
Arya Mazumdar, A K Chaturvedi, Adrish Banerjee
In this letter we present a new construction of interleavers for turbo codes from 3-regular Hamiltonian graphs. The interleavers can be generated using a few parameters, which can…
On the Spread of Random Interleaver
Arya Mazumdar, Adrish Banerjee, A K Chaturvedi
For a given blocklength we determine the number of interleavers which have spread equal to two. Using this, we find out the probability that a randomly chosen interleaver has sprea…
