http://www.biguo100.com/news/52931.html WebThe basic principle of OCDM consists of multiplexing a number of chirp waveforms that are mutually orthogonal with each other and sharing the same bandwidth and time slot. With respect to single chirp modulation, OCDM increases the transmitted data rate by overlapping data in both the time and chirp domain. pace legislation interview

For this method, the transmission bandwidth is divided to several parallel M-FSK transmission, i.e. more than one sub-carrier can be active at a time, for improving the spectral efficiency. pace leonard green

"WebNov 5, 2012 · For instance, the transmission distance of a 30-Gbps DML-based OFDM signal can be extended from 10 km to more than 100 km. Besides, since the dispersion-induced distortion could be effectively mitigated by the equalization, negative power penalties are observed at some distances due to chirp-induced power gain.
