Abstract
A uniform circular array (UCA) is assisted with an analog inverse fast Fourier Fast transform (IFFT)/fast Fourier transform (FFT) precoder to reduce computational complexity in one or more line-of-sight (LoS) multiple-input multiple-output (MIMO) networks. Each port of the UCA includes a steerable miniaturized array with beam steering capability. Analog beam steering is performed via one of the analog IFFT/FFT precoder or one of the steerable miniaturized arrays in a port of the UCA, for improving one or more properties of steering one or more beams toward one or more intended destinations in the one or more LoS MIMO networks.

A method comprising:
- providing a uniform circular array (UCA) that is assisted with an analog inverse fast Fourier transform (IFFT)/fast Fourier transform (FFT) precoder to reduce computational complexity in one or more line-of-sight (LoS) multiple-input multiple-output (MIMO) networks;
- providing, in each port of the UCA, a steerable miniaturized array with beam steering capability;
- and
- performing analog beam steering, via the analog IFFT/FFT precoder and the beam steering capability of the steerable miniaturized arrays in the ports of the UCA, for improving one or more properties of steering one or more beams toward one or more intended destinations in the one or more LOS MIMO networks.
An apparatus comprising:
- a uniform circular array (UCA) that is assisted with an analog inverse fast Fourier transform (IFFT)/fast Fourier transform (FFT) precoder, configured to reduce computational complexity in one or more line-of-sight (LoS) multiple-input multiple-output (MIMO) networks, wherein each port of the UCA includes a steerable miniaturized array with beam steering capability;
- a controller configured to perform analog beam steering, via the analog IFFT/FFT precoder and the beam steering capability of the steerable miniaturized arrays in the ports of the UCA, for improving one or more properties of steering one or more beams toward one or more intended destinations in the one or more LOS MIMO networks.
