Abstract: A display module for a head-mounted display device includes a display assembly, an optical imaging assembly, and a virtual image location adjustment assembly. The display assembly is configured to display an image. The optical imaging assembly is configured to form a virtual image based on the image. The virtual image location adjustment assembly is configured to adjust at least one of the optical imaging assembly and the display assembly to adjust the virtual image to a target location. The virtual image location adjustment assembly adjusts the optical imaging assembly and/or the display assembly.

Abstract: The disclosed systems and methods for frequency domain (FD) local oscillator frequency offset (LOFO) compensation. The method comprising: i) compensating, by an integer Fast Fourier Transform (FFT) bins-based oscillator, LOFO in a received signal by an integer number of FFT bins; and ii) compensating, by a fractional FFT bins-based oscillator, LOFO in the compensated signal by the integer FFT bins-based oscillator with a fine compensation resolution of a fractional number of FFT bins.
