摘要： A system and a method for controlling light distribution in a space including multiple installed light sources (111, 112, 221-223) and an external light source (103, 203). The method includes measuring the luminance levels of light from the multiple installed light sources (111, 112, 221-223) and the external light source (103, 203) at a plurality of measuring areas within the space, controlling the intensity level of each of the installed light sources (111, 112, 221-223) and the amount of light from the external light source entering the space (103, 203) based on the measured luminance levels, and tuning the intensity level of each of the installed light sources (111, 112, 221-223) and the amount of external light entering the space (103, 203) to optimize the conditions such that the mean-squared error between the measured luminance levels and pre-defined target luminance levels for the respective plurality of measuring areas is minimized, and the amount of energy consumed by the multiple installed light sources (111, 112, 221-223) is minimized.

摘要： Enhancements allowing multiplexing of normal and robust data in wireless digital video transmissions using vestigial sideband modulation are implemented as an enhanced vestigial sideband encoder on the studio side and a standard vestigial sideband modulator at the transmitter. The enhanced encoder conventionally processes multiplexed data into encoded packets, with backwards compatible parity data supplied for normal data, then deinterleaves the processed data, removes a trailing portion from each packet, and derandomizes the remainder before forwarding the processed encoded data as MPEG compliant packets to the standard modulator for VSB modulation and transmission.

摘要： A wireless network (300) operates with at least two different types of wireless devices, including Type-A wireless devices (320) that communicate using a first transmission scheme and Type-B wireless devices (310) that communicate using a second transmission scheme. Type-A wireless devices (320) can transmit Type-A beacons (325) using the first transmission scheme. Type-B wireless devices (310) can transmit and receive Type-B beacons (315) using the second transmission scheme. Type-B wireless devices (310) can also transmit Type-A beacons (325) using the first transmission scheme, but cannot receive the Type-A beacons (325). Before establishing communications in a new channel, a Type-B wireless device (310) performs power sensing to detect the presence of any non-Type-B wireless devices (200), and if such wireless devices (200) are detected, it switches to another channel. Otherwise, it transmits a Type-A beacon (325) and a Type-B beacon (315) to establish communications in the channel.

摘要： The system (700), apparatus (600), and method of the present invention provide an hierarchical pseudo-circularly symmetric and full circularly symmetric training sequence structure (100) for high-speed communication system. The hieratical pseudo-circularly symmetric part (101) is preferably used for burst detection, coarse frequency and timing error estimation and AGC gain setting. The full circularly symmetric part (102) is preferably used for channel estimation, fine frequency error estimation. The resulting sequence has a very good peak-to-average power (PAPR) property, making it suitable for many applications. The bandwidth efficiency is also improved due to using symmetric sequences.

摘要： The system, apparatus and method of the present invention provides a single carrier block transmission with guard interval as a means of communications over multi-path channels that enables frequency domain equalization, and therefore, has many of the advantages of OFDM, but does not have some of the drawbacks such as high PAPR and the need for high resolution ADCs. While the use of guard intervals in single carrier communications enables low complexity detection of the signal, it reduces bandwidth efficiency. The present invention improves the bandwidth efficiency by adjusting the length of the guard interval adaptively. Also, by allowing both time-domain and frequency domain equalizations, besides improving bandwidth efficiency, the inventions allows for great flexibility in receiver design.

摘要： A method (200) and system (300) for detecting a received signal, such as a UWB signal, select a first band (210) and search (230) for an autocorrelation peak in the signal in the first band. The autocorrelation peak is compared to a threshold (250), and it is determined that a signal is detected when the autocorrelation peak exceeds the threshold. In response to detecting the signal, the system (300) and method (200) select a second band (260), search (265) for an autocorrelation peak in the signal in the second band, and determine a coarse frequency error (275) in the signal from the autocorrelation peak in the second band. The coarse frequency error in the signal is corrected and a frame synchronization sequence of the signal is detected to complete the synchronization.
