Abstract: Aspects of a digital phase-lock loop (DPLL) with an adjustable delay between an output clock and a reference clock in accordance with phase noise compensation are generally described herein. An apparatus may include processing circuitry configured to, in a first mode, identify a delay element of a plurality of delay elements based on an associated delay value, and set an initial phase difference value to a phase difference value associated with the identified delay element. The processor circuitry may be further configured to, in a second mode, in a second mode, initialize the DPLL using the initial phase difference value, determine a phase error between a reference clock and a feedback clock based on the initial phase difference value, adjust an output clock signal based on the phase error.

Abstract: A method and device for adaptive control of transmission parameters such as data rate, fragmentation and request to send protection. Packet error rates for frames transmitted with and without request to send protection are computed and compared to determine whether error rates are attributable to noise or to collision. If error rates are attributable to noise, data rates may be adjusted and fragmentation may be activated. If error rates are attributable to collisions, request to send protection may be activated or adjusted.
