Abstract: A method for transmitting broadcast signals includes encoding service data; mapping the encoded service data to symbols; building a signal frame including the symbols; and frequency interleaving the symbols in the signal frame. After an interleaving sequence is generated based on a toggle bit, a basic interleaving sequence, and a symbol offset, it is checked whether or not an address of the generated interleaving sequence is within a range of an OFDM symbol being frequency-interleaved. After checking the address, the symbols are frequency interleaved using the interleaving sequence, and when the FFT size is 32K, a single permutation is applied to the basic interleaving sequence, and when the FFT size is 8K or 16K, different permutations are applied to the basic interleaving sequence.

Abstract: In order to reduce the power consumption after a transmitting electronic device in a wireless network has been detected, a receiving electronic device calculates transmit times of subsequent beacons from the transmitting electronic device based on a clock drift of the transmitting electronic device and the beacon period. Then, the receiving electronic device receives the subsequent beacon by opening scan windows that encompass the calculated transmit times. However, because the transmit times are more predictable after the transmitting electronic device has been detected (and the clock drift of the transmitting electronic device is known to the receiving electronic device), the receiving electronic device can reduce the width of the scan windows. In addition, the transmitting electronic device can further reduce the power consumption by increasing the beacon period.

Abstract: A digital network assistant which can detect network anomalies, identify actions likely to remediate them, and assist the user in carrying out those actions. In particular, a digital network assistant constantly monitors data streams associated with the network to determine key performance indicators for the network. When these key performance indicators indicate a network anomaly, the digital network assistant associates it with a digital string to one or more actions likely to remediate similar network issues. The digital network assistant can take these actions automatically or present them to a user to be taken. The system can also aid the user in taking the required actions via an augmented reality interface. In addition, the system can create narratives embedding findings from data analysis eliminating subjectivity. The system can also find optimal parameter sets by continuously analyzing anomaly-free parts of the network and their key performance indicators.
