Overlapped time division multiplexing (OvTDM) is a new type of transmission scheme with high spectrum efficiency and low threshold signal-to-noise ratio (SNR). In this article, the structure of OvTDM is introduced and the sphere-decoding algorithm of complex domain is proposed for OvTDM. Simulations demonstrate that the proposed algorithm can achieve maximum likelihood (ML) decoding with lower complexity as compared to traditional maximum likelihood sequence demodulation (MLSD) or viterbi algorithm (VA).

1998年“世界杯”足球赛开赛前夕，小安安带着一家人的期盼与喜悦在“父亲节”这一天降生于香港基督教联合医院。“安安出生后虎头虎脑，医生、护士都喜欢他，说这个小肥仔真像小老虎，那年恰逢虎年。本想给他取名‘由天’听天由命，但感觉太不进取了就取名‘由安天’。其实我是想4年后带他去看韩日世界杯的。”由仲先生边思考边打开记忆的大门，那时曾开心地盼望他快点长大，父子俩可以一起去世界各地的球赛现场观看“世界杯”
