Information is carried by changing the phase of the carrier. ->BPSK (Binary PSK): Uses two phases (0° and 180°). Very robust, but only 1 bit per symbol. ->QPSK (Quadrature PSK): Uses four phases (0°, ...

Abstract: Digital overlays in composite baseband systems provide a means to integrate new services while maintaining compatibility with existing structures. This paper presents a comparative study of ...

In modern communication systems, digital data is transmitted through different channels where it is affected by noise and interference. Due to this noise, the received data may contain errors.

Abstract: Transmitting high capacity under low SNR conditions is increasingly a challenge in many wireless and free-space communications applications. E.g. in free space optical satellite links ...
