Abstract: An experimental seven digit pulse code modulation (PCM) system has been built for the transmission of monochrome and color television signals over seven pairs of 22-gauge exchange area ...

A novel modulation format is proposed for time-hopping pulse position modulation (TH-PPM) ultra wideband (UWB) communications, where an orthogonal set of user-specific TH codes is employed for M-ary ...

In this paper, the performance of various Pulse Position Modulation (PPM) schemes has been analysed for PIN and APD receivers in the presence of atmospheric turbulence. It is observed that the ...
