Abstract
A variable delay interface configured to introduce a controllable, variable delay between a radio equipment controller and a radio equipment is provided. The interface includes a variable rate change filter, VRCF, having a signal input, a signal output and a rate control input. The VRCF is configured to receive a rate control signal at the rate control inputs and sample an input signal received at the signal input at a sampling rate controlled by a rate control signal to produce a VRCF output signal. The sampling rate is one of greater than and less than a sampling rate of the input signal. The VRCF has a first delay. The interface includes a first in first out, FIFO, buffer having an input and an output, the FIFO buffer configured to store samples of the VRCF output signal received at the FIFO buffer.
