摘要： A receptor of wireless signal in a wireless communication system can be configured to correct for degradations of signal quality. The reception apparatus can include a filter which is configured to create a filtered signal by make corrections to a reception signal which carries a symbol. Based on the created filtered signal, a symbol can be decided and weighted to evaluate the error of the original reception signal. Using the weighting information, a parameter of the filter can be updated to more accurately correct the reception signal.

A set of digital baseband signals from a set of respective additional RF front-ends is adjusted to compensate for errors based on correlation values from a second Golay correlator. A digital baseband signal to be adjusted is selected on a time-sharing basis. The adjusted digital baseband signal from the first RF front-end and the adjusted set of digital baseband signals from the set of respective additional RF front-ends are combined.

摘要： A plurality of chips arranged in a certain layout so as to face free space, and one or more optical elements are included. In the case where signal traffic for electrical communication with a given chip exceeds or is expected to exceed a certain threshold, a plurality of chips involved in communication routing of the excess signal traffic are identified, part of related signal traffic that crosses the plurality of identified chips is converted from an electric signal into an optical signal to re-route the excess signal traffic, and paths of the related signal traffic are dynamically adapted from fixed wired paths between the plurality of chips to optical communication paths formed in the free space.
