Coherent Sideband Modulation (CSB) is a type of modulation used in telecommunications, particularly in analog and digital communication systems. It is a form of amplitude modulation (AM) where the carrier signal is suppressed, and only the sidebands are transmitted. This results in a more efficient use of bandwidth compared to traditional AM, as the carrier does not occupy any bandwidth.
In CSB, the modulating signal is split into two equal parts, one of which is phase-shifted by
The main advantage of CSB is its improved spectral efficiency. Since the carrier is not transmitted, the
However, CSB also has some disadvantages. The absence of the carrier makes it more difficult to demodulate
In summary, Coherent Sideband Modulation is a bandwidth-efficient modulation technique that suppresses the carrier signal, transmitting
