COHERENT BINARY MODULATION TECHNIQUES
WebbAWGN channel adds white Gaussian noise to the signal when signal passes through it. This channel’s amplitude frequency response is flat and phase response is linear for all frequencies [5].The modulated signals pass through it without any amplitude loss and phase distortion. So in such case, fading does not exist but the only Webb24 nov. 2024 · On the symbol error probability for QPSK with quantized observations Abstract: We consider a single-input-single-output (SISO) system with quadrature phase shift keying (QPSK) modulation and derive an easy-to-evaluate expression for the symbol error probability (SEP) when a general n-bit phase quantization is used at the receiver. neil\u0027s service center eagle bend mn
Implementation of Digital Modulation Technique using MATLAB
In a communication system, the receiver side BER may be affected by transmission channel noise, interference, distortion, bit synchronization problems, attenuation, wireless multipath fading, etc. The BER may be improved by choosing a strong signal strength (unless this causes cross-talk and more bit errors), by choosing a slow and robust modulation scheme or line coding scheme, and by applying channel coding schemes such as redundant forward error correction codes. WebbJune 1, 2011 BER Performance BER, BIT ERROR RATE, BPSK, Modulation, Signal to Noise Ratio, SNR Yasir Ahmed (aka John) Modulation is the process by which a binary stream (zeros and ones) is converted to a format that is suitable for transmission over a wired or wireless channel that is prone to noise and interference as well as distortion.
