A method and apparatus are disclosed for transforming information from one semantic environment to another. In one implementation, a SOLx system includes a Normalization / Translation NorTran Workbench and a SOLx server. The NorTran Workbench is used to develop a knowledge base based on information from a source system, to normalize legacy content according to various rules, and to develop a database of translated content. During run time, the SOLx server receives transmissions from the source system, normalizes the transmitted content, accesses the database of translated content and otherwise translates the normalized content, and reconstructs the transmission to provide substantially real-time transformation of electronic messages.

Multiple Steiner codes are transmitted as bursts from multiple base stations (182, 184, 186) having one or more transmit elements (174, 176, 178, 180), with successive bursts providing an extended training sequence for use in channel estimation at an addressed unit (172), such as a mobile handset. Accurate channel estimation is possible through the use of Wiener frequency domain MMSE deconvolution (518) combined with frequency domain spatial decoupling matrices, with quasi-orthogonal pseudo-noise sequences (502, 504, 520, 522) allocated to base stations and their antenna elements. The use of Steiner codes to supplement Wiener frequency domain MMSE deconvolution and frequency domain spatial decoupling results in the possibility of allocating only a single training sequence to each base station provided that the training sequence is of sufficient length to encompass all multiple time-translated channel impulse responses (H). Estimates may be refined iteratively by minimising the MS error of demodulated pilot symbols. Estimates may also be refined by removing taps from the impulse response which are insignificant based on a relatively long-term power-delay profile for the channel.

The present invention relates to the design of an essentially digital system. As one example of digital systems, these may perform real-time transformations on time discrete digitized samples of analogue quantities. An example of such a system is a digital communication system. The transformations on the data can be specified in a programming language and executed on a processor such as a programmable processor or directly on application specific hardware. In accordance with the present invention the digital system is described as a set of threads in a description language. Alternative names for a thread are tasks and processes. The set of threads defines a representation or model of the digital system. In accordance with the present invention, the representation or model is preferably executable at each stage of the design independent of the current level of abstraction of that representation or model. With description language is meant a programming language. In accordance with the present invention each of the threads has a variable having an assignable value which represents the “local time” of said thread, i.e. a time associated only with that thread, which can be used for sequencing the processing of that thread with respect to other threads. With the word “local” is meant that the time is an attribute of the thread only. In accordance with the present invention a means is provided for the designer to assign a delay to each thread or operation within a thread, this delay representing for instance the processing time for the respective operation or thread on a processing engine, e.g. a computer. By this means, not only can the processing of threads be scheduled but also the designer may assign a value representative of an elapsed time for the processing of a thread or operation on a processing engine. In addition, the threads may be refined concurrently, while still keeping their local time so that after the refining process the new representation of the digital system is executable, i.e. the processing of the refined threads can be scheduled without divergence from the specification.

A method of transmitting digital information over a dispersive optical channel includes encoding the digital information into a series of data blocks, wherein each block comprises a plurality of substantially orthogonal frequency domain subcarriers. Each data block is then divided into at least two frequency bands, each band comprising a plurality of contiguous subcarriers. A frequency / time transformation is then performed, in order to form a corresponding plurality of transformed bands, each transformed band comprising a sequence of time domain data samples. A time delay is applied to at least one of the transformed bands relative to at least one other of the transformed bands. The bands are then combined to produce an electrical signal waveform embodying the digital information. Finally, an optical source is modulated using the electrical signal waveform, to produce a corresponding optical signal for transmission over the dispersive optical channel. The invention enables a reduction in the duration of guard intervals that may need to be inserted into the transmitted data blocks, in order to avoid received signal degradation due to inter-symbol interference caused by dispersion in the optical channel. Transmission overheads may thereby be reduced, resulting in an improvement in transmission efficiency.
