Table 3 OOBE suppression techniques group C, principles and drawbacks included
From: Out-of-band emission suppression techniques based on a generalized OFDM framework
Group C (c l  = d l , G = I) | Principle and drawbacks |
|---|---|
AST | Principle: inserting samples between two time blocks |
Drawback: spectrum efficiency loss; data-dependent design | |
Windowing | Principle: some window function applied in time domain |
Drawback: extension of symbol (spectrum efficiency loss) | |
Filtering | Principle: some filter applied in time domain |
Drawback: extension of symbol (spectrum efficiency loss) |
