Table 1 Characters of five example PA envelopes
From: The sensitivity of modulation fidelity on PA envelope variation in OFDM transmitter systems
PA | Envelope characters | PLA(%) |
|---|---|---|
L 0 | DNOP-CISP = 0 dB = DSP-CISP | 100 |
L 1 | DNOP-CISP = 3 dB = DSP-CISP | 75 |
L 2 | 3 dB = DNOP-CISP < DSP-CISP = 6 dB | 50 |
L 3 | 6 dB = DNOP-CISP > DSP-CISP = 3 dB | 50 |
L 4 | DNOP-CISP = 6 dB = DSP-CISP | 0 |
