Lattice Codes Achieve the Capacity of Common Message Gaussian Broadcast Channels with Coded Side Information
Lakshmi Natarajan, Yi Hong, Emanuele Viterbo
Lattices possess elegant mathematical properties which have been previously used in the literature to show that structured codes can be efficient in a variety of communication scen…
Oblivious Transfer over Wireless Channels
Jithin Ravi, Bikash Kumar Dey, Emanuele Viterbo
We consider the problem of oblivious transfer (OT) over OFDM and MIMO wireless communication systems where only the receiver knows the channel state information. The sender and rec…
Capacity of Coded Index Modulation
Lakshmi Natarajan, Yi Hong, Emanuele Viterbo
We consider the special case of index coding over the Gaussian broadcast channel where each receiver has prior knowledge of a subset of messages at the transmitter and demands all…
Index Codes for the Gaussian Broadcast Channel using Quadrature Amplitude Modulation
Lakshmi Natarajan, Yi Hong, Emanuele Viterbo
We propose index codes, based on multidimensional QAM constellations, for the Gaussian broadcast channel, where every receiver demands all the messages from the source. The efficie…
Line of Sight 2 x nr MIMO with Random Antenna Orientations
Lakshmi Natarajan, Yi Hong, Emanuele Viterbo
Line-of-sight (LoS) multiple-input multiple-output (MIMO) gives full spatial-multiplexing gain when the antenna array geometry and orientation are designed based on the inter-termi…
A Comparative Study of Polar Code Constructions for the AWGN Channel
Harish Vangala, Emanuele Viterbo, Yi Hong
We present a comparative study of the performance of various polar code constructions in an additive white Gaussian noise (AWGN) channel. A polar code construction is any algorithm…
