This paper demonstrates the feasibility of layered space-time coding
(STC) in an outdoor image-sensor-based (IS-based) visible light
communication (VLC) system. We examined that for low-resolution
IS-based VLC channel where intensity modulated signals from two
different light emitting diodes (LEDs) are detected at one pixel on
the image plane, STC allows to decouple them, thus receiving data with
no errors. Consequently, STC offers extending the transmission
distance. In the layered STC presented here, additional bit streams
are aligned in the ${2^ntimes 2^n}$,LED array for
increasing the transmission rate per symbol duration for the case
where the spatial resolution is improved. A prototype of three
layered STC is built with an ${8times 8}$,LED array.
Our experimental results validate that
additional bit streams (layer-2 and -3), aligned in the layer-1 STC
matrix pair, are extracted with no errors when the receiver comes
within 155,m and 55,m, respectively, from the LED array, without
decreasing 210,m of the transmission distance of layer-1 bit stream. |
