Microwave Journal Article: Streamlining BER Simulation and Measurement
Bit Error Rate (BER) remains the ultimate quality metric for all communication systems. Emerging 4G systems like LTE specify throughput rate as a metric for system performance. These 4G systems add intelligence by using adaptive modulation based on channel quality, but under the hood, BER is measured while the modulation is adjusted.
