Preliminary results of DSN performance for convolutional codes with a Viterbi decoder

摘要

To determine DSN Telemetry System performance when maximum-likelihood convolutional decoding is employed, testing is being undertaken at DSS 62, Madrid, Spain. Testing hardware and software were developed to evaluate the performance of the DSN in the Viterbi mode with the LV7015 model. Since the bit errors at the decoder output occur in bursts, the test program includes a series of statistical analyses in runs of correct bits and bursts of bits in error.
