Though the maximum likelihood sequence detection decoders can obtain the optimal decoding performance, their computational complexities which increase exponentially with spectral efficiency in OVXDM are unbearable for practical implementations. In this study, a low\u2010complexity multiple\u2010signal joint decoding (MSJD) algorithm for OVXDM signalling is proposed over additive white Gaussian noise (AWGN) channel and extended to frequency selective fading (FSF) channel. Based on a novel joint information\u2010based metric, the proposed algorithm utilises information of each transmitted symbol contained in multiple received signals, and selects the proper number of received signals for decoding to achieve performance maximisation. Moreover, theoretical analysis is provided for the proposed algorithm in both AWGN and FSF channels, which indicates the relationship between performance and number of received signals under different OVXDM encoding parameters including multiplexing waveform and overlapping fold. Simulation results confirm the superior performance of the MSJD algorithm in terms of decoding performance and computational complexity compared with the present approaches.<\/jats:p>","DOI":"10.1049\/iet-com.2017.1402","type":"journal-article","created":{"date-parts":[[2018,3,9]],"date-time":"2018-03-09T21:18:58Z","timestamp":1520630338000},"page":"1273-1282","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Low\u2010complexity multiple\u2010signal joint decoding for overlapped x domain multiplexing signalling"],"prefix":"10.1049","volume":"12","author":[{"given":"Peng","family":"Lin","sequence":"first","affiliation":[{"name":"Key Laboratory of Universal Wireless Communications, Ministry of Education Beijing University of Posts and Telecommunications No. 10, Xitucheng Road, Haidian District Beijing People's Republic of China"}]},{"given":"Yafeng","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Universal Wireless Communications, Ministry of Education Beijing University of Posts and Telecommunications No. 10, Xitucheng Road, Haidian District Beijing People's Republic of China"}]},{"given":"Daoben","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Universal Wireless Communications, Ministry of Education Beijing University of Posts and Telecommunications No. 10, Xitucheng Road, Haidian District Beijing People's Republic of China"}]}],"member":"265","published-online":{"date-parts":[[2018,5,22]]},"reference":[{"key":"e_1_2_8_2_1","unstructured":"IMT\u20102020 (5G) Promotion Group: \u2018White Paper on 5G Network Architecture Design\u2019.
