    摘要: The location of a device may be determined with respect to another device. For example, a locating device may be moved as it measures at least one distance to a target device. The locating device may then generate one or more indications relating to the measured distance or distances. The locating device also may generate one or more indications relating one or more determined directions to the target device. The target device may be moved in a predetermined manner to determine the location of the target device. Each of the devices may employ a single transceiver and a single antenna for the location determination operations.

    摘要: Processing may be performed by a first device on behalf of a second device to offload processing from the second device. In some aspects a device from which processing has been offloaded may be advantageously adapted to consume less power, have a smaller size, and have less complexity. Offloaded processing may be employed to enable a first device to process data for transmission and then send the data to another device for processing. Offloaded processing may be employed to enable a first device to process data on behalf of a second device and then send the processed data to the second device. In some aspects the data may be waveform encoded for wireless transmission between the devices. Offloaded processing may be implemented in a static manner or in a dynamic manner.

    摘要: Auxiliary data subband samples representing an auxiliary data signal are transported in a subband-coded compressed digital audio signal without decompressing the data. A pre-existing packetized data stream is provided to an input of a encoder. Subband audio samples are extracted from the packet stream and normalized if required. The data to be transported modulates data carrier subbands including, for example, a pseudo-noise (PN) spread spectrum signal, each subband of which has a bandwidth corresponding to those of the digital audio signal. The data carrier sequence can also include a sparse PN sequence, sample twiddle sequence, or a bit twiddle sequence. The modulated data carrier sequence is combined with the audio subband samples to form a combined signal in which the auxiliary data subband samples are carried. The combined signal is then multiplexed into the pre-existing packet stream. In a decoder, the combined signal is demodulated to recover the auxiliary data signal. The recovered auxiliary data signal is carried substantially inaudibly in the audio signal and is spectrally shaped according to the audio signal to enhance concealment.

    摘要: Auxiliary data is transported in a primary data signal by hiding the data in the form of colored noise. The colored noise has a spectrum that simulates the spectrum of the primary data signal. The data to be transported is first converted to a spread spectrum signal. The primary data signal is analyzed to determine its spectral shape. The same spectral shape is imparted to the spread spectrum signal, which is then combined with the primary data signal for transmission. The spectral shaping can be performed using time domain modeling and synthesis such as linear predictive coding or by using subband coding techniques such as fast Fourier transforms. A plurality of different auxiliary information streams can be transported on the primary data signal. By adjusting the gain of individual spread spectrum signal carrier(s) and the power of the colored noise, the auxiliary information stream(s) can be rendered at a desired level at, below or above an interference threshold in the primary data signal.
