| Number | Title | Issue Date |
| 6999522 | Constrained-envelope digital communications transmitter and method therefor A constrained-envelope digital communications transmitter (10) places constraints on the envelope of a spectrally constrained, digitally modulated communication signal (42) to lower peak-to-average power ratio without allowing significant spectral regr... | 02/14/2006 |
| 6928121 | Digital transmitter with constrained envelope and spectral regrowth over a plurality of carriers A constrained-envelope digital communications transmitter (10) places constraints on the envelope of spectrally constrained, digitally modulated communication signals (46) converted into diverse frequency channels (54) and combined into a compos... | 08/09/2005 |
| 6731168 | Power amplifier linearizer that compensates for long-time-constant memory effects and method therefor A power amplifier linearizer (12) includes an on-chip portion (60) and an external controller (22). The on-chip portion (60) implements two predistortion circuits (86, 88) desirably configured as look-up tables. One predistortion c... | 05/04/2004 |
