Bit Error Rate (BER) Measurements with ADS and Baseband Studio
应用文章
Verifying Bit Error Rate (BER) and Block Error Rate (BLER) performance can present real challenges to RF engineers. Two major factors should be considered: (1) the number of bits required to produce a statistically meaningful BER/BLER result, and (2) the baseband functionality required to verify coded BER/BLER.
Arbitrary waveform generator (Arb) based solutions allow waveforms to be downloaded from simulation to the signal generator Arb for BER/BLER testing, but are limited by the Arb depth of the signal generator. Depending on the application, this may or may not be suficient.
Another challenge is that RF engineers designing RF receivers may not have access to the baseband functionality required to perform coded BER measurements, which can present a barrier to verifying coded BER - a key receiver design speciication with today’s digital communications signal formats.
The Connected Solutions application described in this note can help in verifying RF BER performance when a large number of data bits are required to achieve a statistically meaningful BER result.
