Title: Digital predistortion system and method for linearizing an rf power amplifier with nonlinear gain characteristics and memory effects
Inventor: BRAITHWAITE RICHARD NEIL
IPC: H04K1/02
Filed: 2005-02-24
Granted: 2011-04-26
Abstract: A system and method of digitally predistorting a transmitter (104) that has a digital input, up-converter (108), and a RF amplifier (110) is disclosed. A  digital predistorter (100) preferably employs three paths for the digital input signal: a linear path (114), a memoryless digital predistortion path (116), and a memory based digital predistortion path (118). The memoryless path (116) is preferably a look up table (LUT) of gain error corrections indexed to the input magnitude or input power. The linear path is separated to preserve the dynamic range of the system and avoid quantization associated with memoryless LUT correction. The memory based digital predistortion path (118) filters the power envelope, or higher even order modes of the input signal magnitude, employing a hierarchical filter, to produce a gain correction. The input signal is modulated by the gain error corrections produced by the memoryless and memory based paths.

Abstract: The invention relates to a method for controlling an electronic power converter (9), which is connected to a direct-current source (12), comprises power conductor switches (10a...10f) that can be deactivated and which is designed to supply a distribution network (2) with three-phase voltage.  According to said method, the currents that flow through the respective power semiconductor switches (10a...10f) are measured, whereby current values that are respectively assigned to the power semiconductor switches (10a...10f) are obtained, the current values are sampled and the sampled current values are digitised to obtain digital current values, the latter being checked by a logic that is implemented in a control unit for the presence of an excess current condition. If no excess current condition is detected, the power semiconductor switches (10a...10f) are activated and deactivated with the aid of a nominal operation controller and if an excess current condition is detected, at least the power semiconductor switches with assigned digital current values that fulfil the excess current condition are deactivated after a pulse block has expired. For the digital current values that fulfil the excess current condition, all power semiconductor switches (10a...10f), which are connected to the positive direct-current connection, are activated and all power semiconductor switches, which are connected to the negative direct-current connection are deactivated or vice versa. For the digital current values that do not fulfil the excess current condition, The power semiconductor switches (10a...10f) are controlled once again by the nominal operation controller.

Abstract: A solid concentrate is provided having a combination of a transition metal present in an amount ranging from 1000 to 40,000 ppm (weight by metal) and a polyester polymer present in an amount of at least 40 wt.% based on the weight of the concentrate. Concentrates made with highly modified polyester polymers are easy to compound with transition metals forming less brittle polymer upon melt extrusion. Bottle preforms and oxygen scavenging bottles can be made from these concentrates by combining solid polyester particles, solid polyamide particles, and solid these concentrate particles c into an melt processing zone, forming a melt, and forming an article directly from the melt. The b*  color and the L* color and the haze levels of the preforms are improved over the preforms made with liquid carriers instead of solid concentrates. The particles are also advantageously simultaneously dried in a drying zone under conditions effective to at least partially remove moisture from the blend to thereby further improve the b* color and L* color.
