Abstract
A method for testing communication channels of a satellite using a 16-bit n-length compression algorithm wherein the most significant bit (MSB) is used to represent the errored or not errored condition of the compression algorithm. Error patterns are read and downloaded into a PC interface card which decompresses the file real time and passes the error pattern to a bit error rate summer board. The bit rate summer board overlays the error pattern onto the communication links of the satellite which causes precise bits to be errored accordingly.
Claims5
A method for testing digital communications channels, comprising:
- generating and storing source files of bit error patterns that have a unique nature relative to bit error patterns of a gaussian or bursty nature;
- passing the error patterns through an interface to a bit summer;
- and
- evaluating each communications channel by overlaying one of the unique error patterns thereon with the bit summer to derive an error pattern comparison for that channel.
