Crest factor reduction is a key component in modern digital amplifier and linearization systems. Using active control of transmit signal error vector magnitude (EVM), Crest Factor Reduction can significantly reduce waveform peak to average power ratio (PAPR), while maintaining spectral purity and improving amplifier linearity, efficiency and cost.

Multi-stage Peak Cancellation Modulation Independent Supports Multi-carrier Waveforms Self Training Algorithm Achieves >70dBc ALCR

The Affarii CFR03 processor is an advanced non-linear cancellation engine that offers low implementation resource and power consumption. The CFR processor is modulation agnostic, supporting single and multi-carrier configurations, and can self training without knowledge of system configuration.

The CFR03 core is designed support peak reduction down to 6dB PAPR dependent on modulation scheme and been qualified for operation with 3GPP WCDMA, LTE and WiMAX standards. Performance analysis and custom design configuration are supported with a PC based simulation environment.

Availability

The CFR03 Crest Factor Reduction processor is available as a standalone IP block as part of the digitalTRX solution. For further information please contact sales@affarii.com
