Bpsk frequency spectrum
WebIn telecommunications, direct-sequence spread spectrum ( DSSS) is a spread-spectrum modulation technique primarily used to reduce overall signal interference. The direct-sequence modulation makes the transmitted signal wider in bandwidth than the information bandwidth. After the despreading or removal of the direct-sequence modulation in the ... WebGFSK stands for Gaussin Frequency Shift Keying modulation. In GFSK, baseband pulses (consists of -1 and 1) are first passed through the gaussian filter before modulation. This makes pulses smooth and hence …
