PSK can also use constant envelope modulation, which maintains the same power level for all symbols, saving energy and reducing interference. Add your perspective Help others by sharing more (125 ...

Phase-shift-keying (PSK) self-homodyne modulation and demodulation using a polarization-multiplexed pilot-carrier with an inverse-return-to-zero (RZ) intensity modulation signal for 2-bit/symbol ...

In most communication systems, power and bandwidth are limited. To achieve more reliability with consuming less power, turbo codes can be used as a powerful coding technique. On the other hand, to ...

Learn how to combine M-ary PSK with other modulation techniques, such as QAM, OFDM, TCM, PPM, and APSK, to improve your data rates, reliability, and efficiency.

In BPSK modulation, digital data of 1 and 0 are represented by 180-degree phase change. Here, one bit per symbol is used. In QPSK modulation these are represented by phase shift of 90 degrees and so ...

Add an FSK modulation block to the Simulink model. Configure the FSK modulation parameters (e.g., carrier frequencies for 0 and 1). Connect the FSK modulator to the same random data source as ASK. PSK ...

Where pin is the number of the PWM capable pin you want to write to, and value is the duty cycle between 0 (always off) and 255 (always on). Explain why 0 volts corresponds to 0 and 5 V corresponds to ...
