Signal Processing for Communication Systems
In digital signal processing, we utilize various elementary sequences for the purpose of analysis. In this series, we will see such sequences. One such elementary sequence is the real-valued exponential sequence. (see the articles on unit sample sequence, unit step sequence, real-valued exponential sequence) A complex-valued exponential sequence in signals and systems is a discrete-time … Read more

Analog (continuous-time) vs discrete-time signals: definitions, sampling bridge, and how sequences relate to digital signal processing.
Keywords: orthogonality, vectors, functions, dot product, inner product, discrete, Python programming, data analysis, visualization This post contains interactive python code which you can execute in the browser itself. Orthogonality Orthogonality is a mathematical principle that signifies the absence of correlation or relationship between two vectors (signals). It implies that the vectors or signals involved are … Read more
OFDM subcarriers are orthogonal over a symbol period; how that yields independent flat bins after the DFT, and how CP protects that orthogonality.
