Abstract: Disclosed herein are a spectrum sensing apparatus and method for a cognitive radio (CCR) network in a non-Gaussian noise environment and an FC apparatus and CCR system using the same. The cooperative cognitive radio (CCR) system includes M cognitive radios (CRs), and a fusion center (FC).

Abstract: One embodiment of the present invention relates to a method for built-in self-measurement (BISM) of jitter components. A built-in self-measurement controller on the host integrated circuit (and, in some cases, a slave controller on a partner integrated circuit) may be used to control various switches to form various loopback circuits. A calibrated jittery data pattern is transmitted through each of the various loopback circuits. On-die instrumentation (ODI) circuitry may then be used to measure intrinsic jitter components for each loopback circuit via data representations such as eye-diagrams, or jitter histograms, or bit error ratio bathtub curves. The intrinsic jitter for link components (i.e. the jitter components such as deterministic jitter (DJ), random jitter (RJ), total jitter (TJ)) may then be determined based on the measured intrinsic jitters for the various loopback circuits. Other embodiments and features are also disclosed.

In these methods, a wireless device listens for beacons that are sent using a low-power wireless protocol. Once the wireless device detects a first beacon at a first location, the wireless device extracts a first beacon region identifier from the beacon and correlates the first beacon region identifier with a first WI-FI™ network that is located at the first location. Next, the wireless device retrieves a first set of credentials for connecting to the first WI-FI™ network. Once the first set of credentials is retrieved, the wireless device uses the first set of credentials to connect to the first WI-FI™ network.
