Exploring Multimode Cellular Transceiver Design: A Short Tutorial

The role that the cellular phone plays in our daily lives is constantly evolving. Conceived as a "mobile" telephone to contrast with a "tethered" telephone, the cell phone functions as a personal assistant, a music player, and a camera, while expanding its primary role as a wireless data transceiver. On average, there is more than one mobile phone per person in this world. Thanks to this all-pervasive reach, several essential services-for example, banking and health care-are now delivered to end users through their cell phones. The protocols or standards governing cellular communication are continually evolving to support this changing landscape in a power-and spectralefficient manner. Mobile technology has witnessed five generations of evolution: from the mobile-phone era ushered in by 2G to the future smartphones that will be powered by the enhanced spectral efficiency of 5G.
