High speed output interface for a multifrequency quaternary phase shift keying signal generated on an industry standard computer
Childs, Robert Daniel.
MetadataShow full item record
A multiple frequency quaternary phase shift keyed signal is generated using a complex Fast Fourier Transform on an industry standard personal computer and is output using direct memory access through a digital to analog converter. The output is permitted at rates of up to the maximum direct memory access rate of the computer. An assembly language program loop, direct hardware output, and high level language output are compared as alternate solutions to the problem of outputting a data stream contained in the computer primary memory.
