Abstract: Multi-input frequency shift keyying can overcome the problem of low band utilization rate in the process of binary frequency shift keyying, and has a wide practical application range. In ...

Abstract: This paper deals with discrete Fourier transform (DFT)-based modulation and demodulation techniques for affine frequency division multiplexing (AFDM), as opposed to using the discrete affine ...

The MN88473 is a digital TV demodulator for DVB-T2/T/C reception. The demodulator has a built-in ADC and de-interleave memory. It has a Low-IF input and outputs TS serial/ parallel. MN88473 is ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...
