摘要： Individual multipath components of digital data symbols sent from a transmitter on at least two carrier frequencies generated from a common clock signal, are received (401) with individual delays and processed by a receiver unit having at least two fingers. Successive channel estimates are determined (402) from received symbols for each finger and each carrier, and an estimated frequency error is determined (404) for each finger and each carrier. A linear equation system is constructed (405), in which each determined frequency error is expressed as a function of a first variable indicative of frequency drift and a second variable indicative of frequency error caused by Doppler effect. The equation system is solved (406) to provide a solution with estimates of the first and second variables for each finger, and an estimated frequency drift is determined (407) from the solution and utilized (408) as feedback signal for adjusting receiver clock frequency.

摘要： The present disclosure provides a frequency offset compensation technique for use by a multi-carrier receiver. Compared with legacy receiver designs, the technique introduces a new function which correlates various frequency offsets of the different carriers involved in multi-carrier signal transmission and reception. This new function can be coupled with an Automatic Frequency Control (AFC) function which can then utilize the correlation information provided by the new function to achieve significantly better frequency error/offset estimation when the carriers are correlated. As a method aspect, the frequency offset compensation technique comprises the steps of receiving signals modulated on a plurality of carrier frequencies, deriving a frequency offset for each carrier frequency to thereby provide a plurality of frequency offsets corresponding to the plurality of carrier frequencies; correlating these plurality of frequency offsets; and controlling compensation of the frequency offsets based on a result of the correlation.

摘要： Eyewear including a see-through display including an optical waveguide module and one or more integrated antennas. In one example, the antenna is disposed on one of the non-active waveguide substrates, which non-active waveguide substrates are used as encapsulants to protect the waveguide active layer from environmental factors and do not have an active optical function in the waveguide operation. In another example, the antenna is disposed on one of the active waveguide substrate surfaces opposite another active waveguide substrate. As a result, there is a large lee-way available in patterning desired antenna shapes, length, and area on these surfaces using optically transparent, high conductivity materials. The antenna is not subject to some design constraints and compromises.
