Samuel Yang's "CDMA RF System Engineering" is a small but complete, accurate, and to-the-point treatment of the IS-95 version of CDMA. It is the best introductory text on the RF system engineering aspects of CDMA networks I have seen. After a quick but comprehensive review of the CDMA processes, radio propagation models, and sundry fundamentals of digital radio techniques; the author turns to the important details of the IS-95 protocol that must be understood in order to consider the RF engineering matters that take up the last third of the book. These system details include: QPSK and OQPSK, power control, handoffs, link structures, access techniques, and call processing. With the system aspects thus covered in an intuitive but rigorous way, the author gets right to the point as he considers the difficulties of RF system engineering: system design, PN management, noise management, and a thorough treatment of general network management techniques. The book is an excellent introduction to the broad subject of CDMA RF engineering for those new to the field.
