The market demand to send high-speed data over wireless has spawned several competing modulation standards for 2.5 Generation and 3 rd Generation systems. EDGE, IS-95B, 1XRTT, 3XRTT, WCDMA, and other standards have been proposed. All of these standards call for envelope varying signals and will produce significant peak to average ratios. This will necessitate receiver and transmitter circuits that must operate with much higher linearity than used in 2 nd Generation hardware. This workshop will address the signal differences between the proposed and existing wireless standards, and the requirements on the RF electronics to support them.
