“…The proposed system with different power imbalance coefficient, i.e. a [ {0.8, 0.2, −0.2}, is compared with both the reference 'optimally'-boosted system [1] (a = 0), and non-iterative Gray-labelled BI-STCM. A resulting EXIT chart [8] at SNR = 4.5 dB is shown in Fig.…”

“…Introduction: In previous work [1] we developed a concept of spacetime diversity scheme for wireless communications, called boosted diversity. The receiver was the same as for well-known bit-interleaved space-time coded modulation with iterative decoding (BI-STCM-ID) [2][3][4].…”

“…straight line in a logarithmic scale. For the reference boosted system [1], as for BI-STCM-ID, the lowest run of the EF bound can be achieved with asymptotically the best 'optimal' labelling [4] of the booster. In this Letter we show how to make the boosted system more flexible and move the EF bound towards lower BERs beyond the limits of the 'optimally'-boosted scheme, developed in [1].…”

“…A formal definition of a M16 a -compliant labeling will be introduced in Sect. 2.3 The author of this paper, inspired by modulation doping, proposed a space-time encoded system, called boosted scheme, in which different labelings, i.e., (Gray, M16 a -compliant) pair, are used within adjacent transmit streams to generate signals carrying the same data [13]. Afterward, he succeeded in applying two optimal BI-STCM-ID labelings-both M16 a -compliant-instead of the (Gray, M16 a -compliant) pair.…”

This paper focuses on 16-QAM labelings of bit-interleaved space-time coded modulation with iterative decoding (BI-STCM-ID). What is contributed is an algorithm to generate (with no random search) optimal labelings for BI-STCM-ID systems with any number of transmit-and receive antennas, transmitting over Rayleigh fading channel. Along with the algorithm, a couple of corollaries are brought, which give an account of the optimal labelings' features. Having a complete set of optimal 16-QAM BI-STCM-ID labelings at hand, it is possible to advance research on labeling diversity scheme by finding all such labeling pairs that-if applied to a system with two different labeling maps within adjacent transmit streams-bring maximum asymptotic coding gain.

“…The fundamental principle of labeling diversity is to apply two different labeling maps for the two adjacent spatial streams of the transmitter. In [20], the BI-StCM-ID was compared with the Boosted scheme [23] equipped with the labeling diversity and in this paper it is referred to as Bit-Interleaved Boosted Coded Modulation with Iterative Decoding (BI-BoCM-ID). Moreover, in [18], for the non-cooperative schemes, various analysis such as Extrinsic Information Transfer (EXIT) chart, distance spectrum, asymptotic gain and Monte Carlo simulations proved the supremacy of the BI-BoCM-ID scheme over BI-StCM-ID (without any labeling diversity).…”

Abstract. Labeling diversity is an efficient technique recently proposed in the literature and aims to improve the Bit Error Rate (BER) performance of Wireless Local Area Network (WLAN) systems with two transmit and two receive antennas without increasing the transmit power and bandwidth requirements. In this paper, we employ labeling diversity with different space-time channel codes such as convolutional, turbo and Low Density Parity Check (LDPC) for both point-to-point and coded-cooperative communication scenarios. Joint iterative decoding schemes for distributed turbo and LDPC codes are also presented. BER performance bounds at an Error Floor (EF) region are derived and verified with the help of numerical simulations for both cooperative and non-cooperative schemes. Numerical simulations show that the coded-cooperative schemes with labeling diversity achieve better BER performances and use of labeling diversity at the source node significantly lowers relay outage probability and hence the overall BER performance of the coded-cooperative scheme is improved manifolds.
