摘要： The ranking quality of a ranked list may be evaluated. In an example embodiment, a method is implemented by a system to access log data, ascertain which entries of a ranked list are skipped, and determine a ranking quality metric from the skipped entries. More specifically, log data that reflects user interactions with a ranked list having multiple entries is accessed. The user interactions include at least indications of which of the multiple entries are selected entries. It is ascertained which entries of the multiple entries of the ranked list are skipped entries based on the selected entries. The ranking quality metric for the ranked list is determined responsive to the skipped entries.

摘要： A baseband processing unit (10) for use in a cellular telephone cell site includes a digital signal processor (20) which serves to process forward voice signals intended for transmission to a mobile unit (12) as well as process the reverse voice signals received from the mobile unit. The digital signal processor further serves to produce a first supervisory audio tone (SAT) for transmission to the mobile unit by generating successive digital SAT samples which are decoded into a continuous tone. In addition, the digital signal processor serves to detect the presence of a second SAT generated by the mobile unit by sampling and processing successive samples of the second SAT and measuring the power thereof.

摘要： The present invention is directed to a cellular telephone cell site base station (10) having a single radio transmitter (40) and radio receiver (14) for transmitting and receiving, respectively, multiplexed frequency-modulated (FM) signals. A filter bank synthesizer (36), associated with the transmitter, multiplexes individual signals for transmission by the transmitter by exponentially modulating the signals to higher frequency bands followed by low-pass filtering and interpolation using discrete Fourier transform techniques. A filter bank analyzer (18), associated with the receiver, demultiplexes multiplexed FM signals received by the receiver by exponentially modulating each signal to its original spectral position followed by low-pass filtering and decimation, using discrete Fourier transform techniques.

摘要： In an arrangement for coding multi-element signals such as used in speech or image processing, a plurality of N element reference signals representable in a prescribed vector space are stored. An N element input signal representable in the prescribed vector space is received and one of the reference signals is selected to represent the input signal. A set of signals each representative of the projection of one of the reference signals on a predetermined orientation in the prescribed vector space and a signal representative of the projection of the input signal on the predetermined orientation are formed. The reference signals are arranged according to their projections on the predetermined orientation. Candidates for the best matching reference signal are selected according to the differences between their projections on the prescribed orientation and the projection of the input signal on the prescribed orientation and the projection difference signals are utilized to determine the reference signal closest to the input signal in the prescribed vector space.

摘要： A phase-modulated signal such as a quadrature phase-shift-keyed (QPSK) signal in a wireless communication system is demodulated by frequency demodulating the phase-modulated signal. The phase-modulated signal is separated into first and second copies, the first copy is phase demodulated to generate demodulated symbols, and the second copy is frequency demodulated to generate, e.g., a measure of the instantaneous frequency of the phase-modulated signal. The instantaneous frequency measure is processed to identify one or more symbol transitions, and the identified transitions are used to generate event signals having signature properties (signature events). These signature events are used in traditional Time Difference of Arrival tdoa algorithms to accurately determine position of a mobile unit in the wireless communication system.
