چکیده
This paper presents a polar transmitter predistortion technique validated with 2.5G mobile communication signals. The methodology used, [1], complements the drain bias modulation with a proper input drive level variation. This technique is believed to improve the linearity, while maintaining the efficiency of such transmitters, and it was validated in a real laboratory test setup.

Statement On The Contribution
Modern digital communication systems utilize OFDM and DS-CDMA signals because of their superior spectral efficiency and multiple access properties respectively. Examples of such systems include digital television (DVB-T), digital radio (DAB) and 3 Generation mobile (WCDMA). A downside to using these signals however is the need to accommodate their very high Crest Factor, also known as Peak-to-A...

The paper proposes a novel pilot-symbol-aided (PSA) technique for fading compensation of digital signals in the mobile environments. In a PSA system, the data sequence at the transmitter is divided into frames of data. A pilot symbol from a known pseudoradom-symbol sequence is inserted periodically into a frame of data symbol for transmission. In a conventional PSA-receiver, these pilot symbols...
