Abstract: A high-rate constrained code is provided to encode/decode channel data. A transformer translates binary channel data into an arbitrary alphabet size. The transformer selects an indicator word and makes forbidden prefix substitutions in the data to be transformed. A finite-state encoder imposes some user-defined constraint on the transformed data before the data is transferred to the channel. The high-rate constrained coding technique may be used to produce high-rate DC-limited and run-length-limited codes. The high-rate code can be used in tandem with error-correcting codes.

Abstract: In a method for encoding and an encoder statistical information is generated and said statistical information (LSB=F(MSB) about the reconstruction values to be used during reconstruction (sometimes called “inverse quantization”) is added to the encoded data signal. The encoded data signal comprises data information providing information on the relation between parts of the original input data removed during quantization and the quantized data. The decoder and decoding method use the information data during reconstruction. This enables reconstruction values to be used during reconstruction that can adapt to the input data statistics thereby improving data reconstruction and reducing the quantization error. The reconstruction at the decoder is guided by information data which is gathered at the encoder, this information data being derived from determining statistical information on the removed parts of the input data in relation to the after quantization remaining quantized data.

For a given relative delay introduced between the signals, the resultant combined value indicates whether the introduced delay brings the transitions in the two signals into coincidence. The process can be repeated for other introduced delays to determine the amount of delay between the two signals.

Abstract: Apparatus and methods are provided for use in a receiver that receives global positioning data from one or more satellites above the Earth's surface. The apparatus and methods involve detecting a change in at least one parameter associated with the receiver and determining if the change in the at least one parameter is to be treated as erroneous. As a result of determining if the change in the at least one parameter is to be treated as erroneous, a further action may be performed. Determining if the change is to be treated as erroneous may include, for example, detecting changes in more than one parameter and determining if the changes are coincident. Detecting a change in at least one parameter may also enable the receiver to predict the presence and magnitude of multipath components of signals, predict changes in an environment local to the receiver, predict large errors in position estimates determined by the receiver and modify an acquisition and tracking strategy used by the receiver.

Abstract: The invention provides a method of processing signals from a satellite positioning system in which a user inputs an approximate indication of current position, and this is used when processing satellite samples to reduce the processing required or increase the reliability. This approach avoids the need for an automated approximate location system (for example using cellular telephony). This represents a change in the way GPS (or other satellite systems) is used. Instead of relying on a GPS system to provide a location in entirely automated manner, the approach is for the user to give an approximate location (which will generally be known), and for the GPS system then to correct this and provide an accurate location. This approach can enable the GPS system to function in areas where it would normally be unreliable.
