Implementing Digital IF & Digital Predistortion Linearizer Functions with Programmable Logic
Introduction
Mobile communication is quickly becoming the primary mode of communication for most of the developed world. Based on 2.5G technologies, most countries now have data services available that will bring about significant changes in the way people exchange business and personal information. With the increasing popularity of data services, greater amounts of bandwidth are required. One of the key ways to increase the bandwidth is to use diversity techniques, which have been incorporated in most of the 3G (bay station modem) standards specifications.
