Emerging 4G Communications Systems: Making Digital Pre-Distortion Fast and Practical for all Engineers

A transition is now underway in the wireless communications industry as wireless service providers migrate from 3G to 4G technologies like LTE-FDD, LTE-TDD and WiMAX™ to keep pace with emerging devices like smart phones. For the engineer, this transition means a host of new challenges. For example, they must determine exactly how far away their design is from being able to operate in 4G and whether or not it will need to be completely redesigned to do so. The hardware must also meet or exceed standards-based performance requirements such as ACPR, EVM or throughput (e.g., BLER, BER and PER), while meeting product design goals.
