Orthogonal space–time block codes for free-space IM/DD optical links

Premaratne, M. and Zheng, F.-C. (2007) Orthogonal space–time block codes for free-space IM/DD optical links. Electronics Letters, 43 (15). pp. 822-823. ISSN 0013-5194 doi: 10.1049/el:20073712

Abstract/Summary

Use of orthogonal space-time block codes (STBCs) with multiple transmitters and receivers can improve signal quality. However, in optical intensity modulated signals, output of the transmitter is non-negative and hence standard orthogonal STBC schemes need to be modified. A generalised framework for applying orthogonal STBCs for free-space IM/DD optical links is presented.
