Histogram equalization is an image processing technique that redistributes pixel intensities to transform an image's histogram from a concentrated range to a uniform distribution across the entire grayscale spectrum. This non-linear stretching operation enhances contrast by making pixel counts approximately equal within intensity ranges. While effective for improving local contrast, it may reduce grayscale levels and cause unnatural over-enhancement in high-peak histograms. Implementation typically involves calculating cumulative distribution functions and mapping original intensities to new values.

Generate a uniformly distributed white noise signal with zero mean and power p, plot its waveform, and validate its distribution. Additionally, generate zero-mean Gaussian white noise with power 0.1, sinc signals, chirp signals, and demonstrate linear convolution operations with implementation details.

A 16-element uniform linear array with half-wavelength spacing employs uniformly weighted conventional beamforming. Five uncorrelated far-field target sources transmit signals from azimuth angles -40°, -42°, -5°, 30°, and 33° relative to the array, each with equal 10dB signal-to-noise ratio at reception. Comparative analysis is performed between beamspace and element-space MUSIC algorithms for direction of arrival estimation.
