Power Efficient Channelizer for Software Defined Radio

Multiple communication channel support in RF transmission, such as that in a Software Defined Radio (SDR) warrants the use of channelizers to extract required channels from the received RF frequency band and to perform follow-on baseband processing. This work describes the process of channelization as it applies to low power and high-efficiency applications in wireless and Satellite Communications (SATCOM) domains. Smaller bandwidths and changing requirements of bandwidth calls for a programmable channel selection mechanism whereby channels and the resulting bandwidth can be selected based on target application which is the primary principle in the Software Defined Radio based systems. Evolving wireless standards, advances in FPGA technologies available at a much lower Non-Recurring Engineering (NRE) costs than those for a comparable custom designed ASIC make programmable channelizer a viable solution. Radiation hardness is an essential requirement for parts used in space systems. This book addresses the importance of methods to meet radiation requirements: selection of robust technologies and hardening by design.
