Decoder Description Language (DDL)


The user can define and create his own decoders, integrate existing ones or modify the integrated standard decoders. The evolutionary growing Decoder Description Language (DDL) is the most suitable toolbox for this task.

More than 100 commands for pre-processing, search, reading, transformation, error correction and output formatting are easy to learn and use like a standard programming language. The instruction set is not only designed for simple recognition and synchronization tasks, but also for complex channel decoding procedures. All supplied decoders were built on this basis. Where available, users can use these decoders as models for their own solutions.
The starting point is a demodulated bit stream supplied by an appropriately parameterized demodulator. DDL allows the analysis and processing of bit streams to generate decoded message content. In this way, even modern channel decoding methods can be applied in just a few steps.

The decoders can be used in other go2SIGNALS installations (e. g. go2MONITOR) as well as in other wireless monitoring systems with the same technology (PLATH). The DDL ensures high decoding quality, i. e. fast synchronization, selectivity, correction capabilities, etc.

The powerful programming language (DDL) reduces the size of the decoder and thus the possible number of errors, which reduces the development time.
From the DDL it is also possible to call DLL's in C, C++ or other programming languages.
