Abstract

低密度奇偶檢查碼 廣義空間位移調變 大型多輸入多輸出系統 LDPC code Generalized Space Shift Keying schemes Massive MIMO System
Massive MIMO systems and Generalized space shift keying(GSSK) mod- ulation are studied in recently years. The former uses large scale antenna arrays in wireless communication, and the latter encodes the information onto the selection of antenna indices. In detail, massive MIMO improves the energy eciency and throughput compared with traditional MIMO sys- tems, and GSSK reduces the transceiver complexity and increases spectral eciency in massive MIMO. There are amount of researches discussed the hard-decision detections about GSSK. In this thesis, we present the soft- decision detections with LDPC code. Also, we compare to MAP detection with a tight performance loss. Finally, extrinsic information transfer(EXIT) chart is applied to design the LDPC code with each detector. We also show the simulation result and compare with the LDPC code in AWGN channel.
