Abstract
It has been shown that the data throughput of an optical modulating retroreflector (MRR) system can be enhanced by use of spectrally efficient M-ary quadrature amplitude modulation (M-ary QAM). It has been demonstrated that this MRR system has sufficient dynamic range to support up to 64-QAM at 30 Mbit/s in a 6.75 MHz channel bandwidth.
