NanoSemi - The Technology

 

DPD – Digital Pre-Distortion – The exploding need for higher data rates leads to more complex modulation schemes and higher bandwidth requirements challenging radio design engineers to optimize for efficiency and linearity. NanoSemi is offering a solution based on a unique approach to known DPD techniques that addresses nonlinearity and other impairments in the entire signal chain from DAC to PA in transmitters and from LNA to ADC in Receivers.

CFR – Crest Factor Reduction – LTE and the underlying OFDM signals come with high peak to average power ratio requirements and the demands are increasing with the trend to carrier aggregation. NanoSemi’s CFR technology operates in the sweet spot of highest data rate and power consumption – or EVM and PAPR respectively – close to the theoretical limits.

PPC – Post-processing compensation is a proprietary NanoSemi technology based on an efficient characterization process for nonlinear devices managing all real life situations including but not limited to 3GPP wideband signals, GSM, multitone and the combination of those.
