Effect of Noise on BPSK Constellation - Simulation


Binary Phase Shift Keying (BPSK) Simulation

BPSK is a type of digital modulation where each bit is represented by one of two possible phases of a carrier signal:

0 → -1,   1 → +1

The transmitted BPSK signal can be written as:

s(t) = √(2E_b) * cos(2Ī€f_c t + Ī€b),   b ∈ {0,1}

When transmitted over a noisy channel, Additive White Gaussian Noise (AWGN) affects the signal. At the receiver, the demodulated signal is compared with a threshold (0) to detect the bit.

This simulation demonstrates the effect of noise on BPSK constellation points and allows you to calculate the Bit Error Rate (BER).

Channel Impulse Response (CIR)

📘 Overview & Theory 📘 How CIR Affects the Signal 🧮 Online Channel Impulse Response Simulator 🧮 MATLAB Codes 📚 Further Reading What is the Channel Impulse Response (CIR)? The Channel Impulse Response (CIR) is a concept primarily used in the field of telecommunications and signal processing. It provides information about how a communication channel responds to an impulse signal. It describes the behavior of a communication channel in response to an impulse signal. In signal processing, an impulse signal has zero amplitude at all other times and amplitude ∞ at time 0 for the signal. Using a Dirac Delta function, we can approximate this. Fig: Dirac Delta Function The result of this calculation is that all frequencies are responded to equally by δ(t) . This is crucial since we never know which frequenci...

Q-function in BER vs SNR Calculation

Q-function in BER vs. SNR Calculation In the context of Bit Error Rate (BER) and Signal-to-Noise Ratio (SNR) calculations, the Q-function plays a significant role, especially in digital communications and signal processing . What is the Q-function? The Q-function is a mathematical function that represents the tail probability of the standard normal distribution. Specifically, it is defined as: Q(x) = (1 / sqrt(2Ī€)) ∫ₓ∞ e^(-t² / 2) dt In simpler terms, the Q-function gives the probability that a standard normal random variable exceeds a value x . This is closely related to the complementary cumulative distribution function of the normal distribution. The Role of the Q-function in BER vs. SNR The Q-function is widely used in the calculation of the Bit Error Rate (BER) in communication systems, particularly in systems like Binary Phase Shift Ke...
