Abstract
This paper describes a look up table (LUT) based digital predistortion system usable for EDGE (enhanced data for GSM evolution) handset transmitters. The system is memoryless and capable of improving system efficiency and performance in terms of the leakage power at offset frequencies and error vector magnitude (EVM). Minimum system requirements on wordlength and LUT size have been investigated. It is shown that a LUT having about 500 coefficients and a system wordlength of 13 bits are sufficient for EDGE. The proposed system is simple and can be easily implemented in handsets in order to improve the overall system performance.
