Equalizer
The equalizer is a device that attempts to reverse the distortion incurred by a signal transmitted through a channel. In digital communication its purpose is to reduce inter symbol interference to allow recovery of the…
Windowing Signals
Use smoothing windows to improve the spectral characteristics of a sampled signal. When performing Fourier or spectral analysis on finite-length data, you can use smoothing windows to minimize the discontinuities…
Cyclic Prefix
The cyclic prefix acts as a buffer region or guard interval to protect the OFDM signals from intersymbol interference. This can be an issue in some circumstances even with the…
What is OFDM
OFDM, Orthogonal Frequency Division Multiplexing is a form of signal waveform or modulation that provides some significant advantages for data links. Accordingly, OFDM, Orthogonal Frequency Division Multiplexing is used for…
What is GMSK Modulation
Gaussian Minimum Shift Keying, or to give it its full title Gaussian filtered Minimum Shift Keying, GMSK, is a form of frequency modulation that is used in radio communications systems.…
What is MSK: Minimum Shift Keying Modulation
Minimum shift keying, MSK, is a form frequency modulation based on a system called continuous-phase frequency-shift keying. Minimum shift keying, MSK offers advantages in terms of spectral efficiency when compared…
QPSK modulation and generating signals
Quadrature phase-shift keying is now the mainstream method used for modulation in cable modems, satellites, and numerous other wireless communication schemes. The signature constellation pattern of QPSK and related digital…
Quadrature Phase Shift Keying
The Quadrature Phase Shift Keying QPSK is a variation of BPSK, and it is also a Double Side Band Suppressed Carrier DSBSC modulation scheme, which sends two bits of digital information at a time, called…
Structure Of Wireless Communication Link
Structure of wireless communication link The structure of wireless communication link in Wireless operations permit services like long-range communications which are impossible or impractical to implement with the wires usage in…
