内容説明 High Speed Packet Access (HSPA) is a collection of two mobile telephony protocols， High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA). Allowing networks based on the Universal Mobile Telecommunications System to achieve data rates of several megabits per second， these powerful protocols are ideal for applications ranging from file transfer to multimedia streaming. From basic concepts to research grade material， the HSDPA/HSUPA Handbook provides technical information on all aspects of HSDPA/HSUPA. With contributions from 30 experts from around the world， this comprehensive HSPA reference provides a global and authoritative perspective of this rapidly emerging technology. Investigates the relationship between HSDPA/HSUPA and UMTS Describes the benefits of HSPA and its technical enhancements Explains packet flows in HSDPA Explores migration issues associated with HSPA Considers receiver designs and multi-user extensions to MIMO HSDPA Presenting information in a well-structured manner for ease of reference， this book presents accurate and up-to-date information on the full spectrum of topics related to HSPA technology， including future directions. The ideal desk reference for designers and planners of contemporary wireless communication networks， this book can also be adopted as a textbook for graduate and research-oriented courses that deal with HSPA.
