Bit error rate measuring system |
摘要 |
A bit error rate of M-phase digital phase-modulated waves is measured by the steps comprising multiplying a received wave by M, phase-detecting the M-multiplied signal either directly or after frequency conversion, detecting errors by comparing the output level of the phase detection with a threshold, and counting the number of such errors. By employing above mentioned system, a bit error rate can be measured easily and accurately by a simple circuit structure.
