How Do Beams Look Like?

In the article on classical beamforming, we discussed the interaction of the electromagnetic waves with the antenna array without any

Once upon a time, an antenna was viewed as a simple device to transmit and receive an electromagnetic wave, much

This post treats the signals in continuous time which is different than the approach I adopted in my book. The

An Analog to Digital Converter (ADC) samples a continuous-time signal to produce discrete-time samples. For a digital signal processor, this

The performance of a digital communication system is quantified by the probability of bit detection errors in the presence of
