Classification: CPC H  G | IPC H

Claim 10:
11. A device for wireless communications, comprising:
a wireless transceiver configured to receive a transmission of a packet; and
one or more processors programmed to:
read a first value of a system timer and storing the first value as an arrival time-stamp;
decode and process the packet;
send the processed packet to an output of the device;
when the processed packet is sent, read a second value of the system timer;
calculate a departure time stamp by adding the second value to a fractional delay of a sample rate converter of the device;
calculate a throughput delay for the device;
calculate an error signal as a difference between the calculated throughput delay and a constant preconfigured delay; and
use the error signal to calculate an adjustment stimulus for the sample rate converter to maintain the calculated throughput delay equal to the preconfigured delay.
