摘要
In this letter, we propose a new Space Shift Keying (SSK)-based modulation that maps the information onto the antenna indices. The proposed Bi-Space Shift Keying (BiSSK) scheme extends SSK by employing a dual set of antenna indices, one associated with a real number and the other with an imaginary number. The proposed BiSSK preserves the advantages of low receiver complexity of SSK and yet doubles its transmission rates, with negligible performance penalty. The proposed BiSSK outperforms Generalized Space Shift Keying (GSSK) at the same given target transmission rate, as demonstrated by both error-probability analyses and simulations.
