Optical Nyquist pulse generation and transmission have emerged as pivotal technologies in the pursuit of maximising data throughput and optimising spectral efficiency in modern fibre‐optic ...

Direct conversion, or zero IF, receivers are popular in applications where the need to reduce power consumption, reduce costs and extend battery life are behind requests to use 'all the Nyquist ...

This rule of thumb enables us to estimate the highest frequency to worry about for a data signal. Spoiler summary: At the Tx, it is 2.5× the bitrate. At the Rx, in a lossy channel, it is the Nyquist: ...
