Crest Factor Reduction (CFR) is a critical technique in wireless communications, used to lower the peak-to-average power ratio (PAPR) of multi-carrier and multi-user signals. High PAPR can lead to inefficiencies within RF power amplifiers, driving the need for effective solutions such as CFR to ensure optimal performance. By minimizing PAPR, Faststream's CFR IP simplifies power supply design and cuts down the peak power requirements in amplifiers, enhancing their power efficiency.
CFR is often deployed alongside Digital Pre-Distortion (DPD) within transmission chains, functioning as part of the broader strategy to linearize power amplifiers. This IP enables system configurability for various transmission architectures, offering compatibility with single-channel, multi-channel, and mixed-mode systems. Faststream has developed their CFR IP using advanced modeling techniques in Structural Verilog and MATLAB, facilitating robust design exploration and verification phases.
Key features of the CFR IP include its adaptability to digital pre-distortion (DPD) and envelope tracking technologies, with versatile configurations that support multiple antennas and clock-to-sample ratios. By providing significant PAPR reduction, Faststream's CFR IP enhances the overall reliability and efficiency of wireless network systems, making it a valuable asset in modern telecommunications setups.
