On the Achievable Rate of OFDM With
IndexModulation
Abstract— Orthogonal frequency division multiplexing with index modulation (OFDM-IM) is a recently developed transmis-sion technique that extends the principle of spatial modulation to OFDM sub carriers.In this paper,the performance of OFDM-IM is studied in terms of the achievable rate assuming an -ary constellation and that channel state information is available at the receiver. A closed-form lower bound is derived, based on which an inter leaved grouping method is proposed for the use of subcarriers. < final year projects >
