Index coded PSK modulation [PDF]
2016 IEEE Wireless Communications and Networking Conference, 2016 In this paper we consider noisy index coding problem over AWGN channel. We give an algorithm to map the index coded bits to appropriate sized PSK symbols such that for the given index code, in general, the receiver with large amount of side information will gain in probability of error performance compared to the ones with lesser amount, depending upon

Space-Time Index Modulation [PDF]
2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017 In this paper, we present a new multi-antenna modulation scheme, termed as {\em space-time index modulation (STIM)}. In STIM, information bits are conveyed through antenna indexing in the spatial domain, slot indexing in the time domain, and $M$-ary modulation symbols. A time slot in a given frame can be used or unused, and the choice of the slots used

Multidimensional index modulation in wireless communications [PDF]
2017 Information Theory and Applications Workshop (ITA), 2017 In index modulation schemes, information bits are conveyed through indexing of transmission entities such as antennas, subcarriers, times slots, precoders, subarrays, and radio frequency (RF) mirrors. Index modulation schemes are attractive for their advantages such as good performance, high rates, and hardware simplicity.
