Pulse Modulation: • Transmits analog information by sampling continuous waveforms at regular intervals. • Information transmitted only at sampling times with synchronizing signals. • Original ...

A project focused on sampling, pulse code modulation (PCM), and adaptive differential pulse code modulation (ADPCM) techniques using MATLAB. The implementation includes signal conversion and bit rate ...

In OCDMA systems, pulse position modulation (PPM) and multi-code modulation (MCM) have been proven as efficient methods for respectively mitigating multiple access interference (MAI) and dispersion.

For pt.I see ibid., vol.50, p.2018-31 (2002). In part I, we proposed and investigated a hybrid pulse position modulation/ultrashort light pulse code-division multiple-access (PPM/ULP-CDMA) system for ...
