We propose two types of full-rate integer STBCs (ICs) for 2 × 2 Multiple-Input Multiple-Output (MIMO) fading channels. A unique property of ICs is the presence of integer coefficients in the code structure, which enables reduced numbers of processor bits for the encoder. Due to the presence of integer coefficients ICs can be encoded with as low as 3, 5, and 7 bits for 4, 16, and 64-QAM constellations, respectively. We show that ICs are fast Maximum Likelihood (ML) decodable with the worst-case complexity of O(2M2.5) for square M-QAM constellation. We also show that ICs have low Peak-Average-Power-Ratio (PAPR) values. Through computer simulations, we show that ICs outperform the finite-precision versions of the Golden code and the Silver code. Importantly, one of the proposed types of ICs are within a constant gap of 2 dB from the infinite-precision versions of the Golden code and the Silver code for 4, 16, and 64-QAM constellations, at moderate to high SNR values.

ConferenceIEEE International Conference on Communications 2013
Abbreviated titleICC 2013
OtherThe International Conference on Communications (ICC) is one of the two flagship conferences of the IEEE Communications Society, together with IEEE Globecom. Each year the ICC conference attracts about 2-3.000 submitted scientific papers, a technical program committee involving about 1.500 experts provides more than 10.000 reviews, the conference being finally attended by 1.500 - 2.000 professionals from all around the world. IEEE ICC is therefore one of the most significant scientific events of the networking and communications community, a must-attend forum for both industrials and academics working in this area.
