From both a technical and a practical point of view, there is much to examine, evaluate and understand in the new 3GPP LTE cellular technology before its projected deployment in 2010. This book, written by Agilent engineers in collaboration with Anite engineers and LTE expert Dr K. F. Tsang, offers valuable insight into the LTE air interface at the physical layer. Chapters also cover the upper layer signalling and system architecture evolution (SAE). Basic concepts such as MIMO and SC-FDMA, the new uplink modulation scheme, are introduced and explained, and the authors dig into the challenges of verifying the designs of the receivers, transmitters and protocols of LTE systems. The latest information on RF and signalling conformance testing is delivered by authors participating in the 3GPP standards committees.
