Popis:	As the interest in the deployment of Free Space Optical (FSO) links gains momentum, its becoming important to investigate the implementation of proposed higher state modulation schemes. M-ary PPM promises significant performance enhancement and this paper gives results about an experimental VHDL based FPGA implementation of a 256-ary PPM modem. The discussed chip design proves the capability of M-ary PPM as an implementable solution for future FSO systems. This preliminary design provides a suitable starting point for an integrated solution in the next generation FSO systems.
