Method and apparatus for an advanced radio system

A method of an advanced communication system, the method comprising:

• generating a first signal with a polyphase coding based on a discrete Fourier transform (DFT) spread orthogonal frequency division multiplexing (OFDM) with at least one constant amplitude zero autocorrelation (CAZAC) sequence in accordance with a configuration condition, wherein the first signal comprises a polyphase sequence;
• applying a digital transmit beamforming to the generated first signal;
• converting the first signal to analog from digital;
• modulating the converted first signal with an energy source;
• emitting, using at least one energy emit element, the modulated first signal;
• detecting a second signal comprising at least a portion of the emitted first signal that is reflected from at least one object in a scene in a field-of-view;
• demodulating the detected second signal;
• converting the second signal to digital from analog;
• converting the converted second signal to a computational image;
• and
• generating a 3D image by applying coherent detection to the computational image.
