New Results on Single User Massive MIMO
Kasturi Vasudevan, Surendra Kota, Lov Kumar +1
Achieving high bit rates is the main goal of wireless technologies like 5G and beyond. This translates to obtaining high spectral efficiencies using large number of antennas at the…
Turbo Coded Single User Massive MIMO
K. Vasudevan, A. Phani Kumar Reddy, Gyanesh Kumar Pathak +1
This work deals with turbo coded single user massive multiple input multiple output (SU-MMIMO) systems, with and without precoding. SU-MMIMO has a much higher spectral efficiency c…
On the Probability of Erasure for MIMO-OFDM
K. Vasudevan, A. Phani Kumar Reddy, Gyanesh Kumar Pathak +1
Detecting the presence of a valid signal is an important task of a telecommunication receiver. When the receiver is unable to detect the presence of a valid signal, due to noise an…
Data Detection in Single User Massive MIMO Using Re-Transmissions
K. Vasudevan, K. Madhu, Shivani Singh
Single user massive multiple input multiple output (MIMO) can be used to increase the spectral efficiency, since the data is transmitted simultaneously from a large number of anten…
Near Capacity Signaling over Fading Channels using Coherent Turbo Coded OFDM and Massive MIMO
K. Vasudevan
The minimum average signal-to-noise ratio (SNR) per bit required for error-free transmission over a fading channel is derived, and is shown to be equal to that of the additive whit…
Linear Prediction based Data Detection of Convolutional Coded DQPSK in SIMO-OFDM
Vineel Kumar Veludandi, K Vasudevan
Data detection of convolutional coded differential quaternary phase shift keyed (DQPSK) signals using a predictive Viterbi algorithm (VA) based receiver, is presented for single in…
Multi-Pair Two Way AF Full-Duplex Massive MIMO Relaying with ZFR/ZFT Processing
Ekant Sharma, Rohit Budhiraja, K Vasudevan
We consider two-way amplify and forward relaying, where multiple full-duplex user pairs exchange information via a shared full-duplex massive multiple-input multiple-output (MIMO)…
Full-Duplex Massive MIMO Multi-Pair Two-Way AF Relaying: Energy Efficiency Optimization
Ekant Sharma, Rohit Budhiraja, K Vasudevan +1
We consider two-way amplify and forward relaying, where multiple full-duplex user pairs exchange information via a shared full-duplex massive multiple-input multiple-output (MIMO)…
Coherent Detection of Turbo-Coded OFDM Signals Transmitted through Frequency Selective Rayleigh Fading Channels with Receiver Diversity and Increased Throughput
K. Vasudevan
In this work, we discuss techniques for coherently detecting turbo coded orthogonal frequency division multiplexed (OFDM) signals, transmitted through frequency selective Rayleigh…
Design and Development of a Burst Acquisition System for Geosynchronous Satcom Channels
K. Vasudevan
The key contribution of this work is to develop transmitter and receiver algorithms in discrete-time for turbo- coded offset QPSK signals. The proposed synchronization and detectio…
