EDITORIAL

The FRQNT’s mid-term evaluation process of ReSMiQ ended with a meeting between the center’s management and the evaluation committee at the FRQNT offices in Montreal. We are awaiting the verdict of this committee, but we are confident that the result would be positive.

After an evaluation of all our scholarship and financial aid programs, it was decided to improve them in order to better serve the research members and to increase support for students in their studies and research. We invite you all to consult the web portal to know the new rules of our various programs.

As for the technical activities of our members, we have completed the 7th edition of the ReSMiQ Innovation Day (JIR) which was enriched by numerous technical demonstrations. in addition to lectures given by two ReSMiQ members (Paul-Vahé Cicek from UQAM and Wei-Ping Zhu from Concordia University) and Jeyanandh Paramesh from Carnegie Mellon University in the United States (DL IEEE SSCS). Many thanks and congratulations to all the students who submitted their project and congratulations to the winners of the contest. Furthermore, after an undeniable success in Montreal last June, the 17th NEWCAS conference will be held in Munich between June 23 and 26, 2019. We congratulate the team that completed NEWCAS’18 with great success. It is for this purpose that we strongly encourage ReSMiQ members to submit their publications in large numbers and thus continue the tradition of quality of this conference initiated in 2003.

ReSMiQ’s management team wishes you a happy holiday season and a Happy New Year 2019.

RESEARCH CONTRIBUTIONS

On Increasing the Slow-Fading Channel Diversity Using Block-Coded MIMO-OFDM With Reconfigurable Antennas

In this paper, we propose a new block coding scheme to increase the diversity gain of multiple-input-multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems over slow-fading wireless channels. We assume that the antenna elements at the transmitter are reconfigurable and capable of independently changing the physical characteristics of their radiation patterns. The composite right-left handed leaky-wave antenna is an example of reconfigurable antennas with such characteristics. We use this feature of the antennas and develop a block coding scheme that exploits, in addition to the spatial and frequency diversity, a new additional degree of diversity, which is called state diversity. We determine the maximum achievable diversity order of the proposed coding scheme in spatially correlated frequency-selective channels. To demonstrate the performance of the proposed block coding technique, we provide numerical results and compare them with those of the previously developed coding schemes for MIMO-OFDM systems. The results indicate that the proposed code achieves significantly higher diversity and coding gain, even in spatially correlated channels, compared with the existing counterparts.

Fig. 2. The bit error rate (BER) versus SNR for a reconfigurable multiantenna system with Mt=2, P=2, Mr=1 in a two-ray channel with a delay spread of 20 μs. Our proposed coding scheme outperforms the codes presented before by about 6 and 4 dB, respectively. This performance improvement demonstrates the superiority of the proposed QOSF scheme, which can exploit the extra radiation pattern diversity gain offered by the use of reconfigurable antenna elements.
