Using PSK with multiple (4, 8, or more) phase changes, this method allows more bits to be transmitted over the same bandwidth as compared to FSK. 8PSK (8 Phase Shift Keying) is a phase modulation ...

A fully functional modem implemented entirely on an Arduino. This is a work in progress. Right now only Bell 103 (as an answering station) is supported. Simply hook up a 6-bit R2R DAC to PORTD (D8-D13 ...

Arduino + LTE Modem Communication Overview: I’ve developed an Arduino code designed to seamlessly transmit sensor data to the Hologram platform from an Arduino Nano equipped with a SIM7000 module.

This paper presents the implementation of Phase Shift Keying (PSK) baseband modem on Digital Signal Processor (DSP). Different level of PSK modulation schemes were used which were 16-psk, 32-psk, ...
