MATLAB implementation of QPSK modulation employing pseudo-random sequences and low-pass filtering techniques, with visual output analysis available through accompanying graphs
Detailed Documentation
In this article, we implement a MATLAB program using the QPSK modulation scheme. The program utilizes pseudo-random sequences as input data sources and incorporates low-pass filtering techniques for signal processing. Key implementation aspects include generating pseudo-random sequences using MATLAB's rand() or randi() functions, implementing QPSK modulation through constellation mapping and carrier multiplication, and applying low-pass filters using functions like filter() or designfilt() to smooth the transmitted signal. For deeper understanding of the program execution flow and signal characteristics, readers can refer to the accompanying graphical outputs that demonstrate signal waveforms, constellation diagrams, and spectral analysis before and after filtering.
