3G Long Term Evolution Baseband Processing with Application-Specific Processors
Data rates in the upcoming 3G long term evolution
(LTE) standard will be manifold when compared to the current
universal mobile telecommunications system. Implementing
receivers conforming with the high-capacity transmission techniques
is challenging due to the complexity and computational
requirements of algorithms. In this study, the software defined
radio (SDR) is targeted and the four essential baseband functions
of the 3G LTE receiver, namely, list sphere decoding, fast
Fourier transform, QR decomposition, and turbo decoding, are
addressed and the functions are implemented as application specific
processors (ASPs). As a result, the design space that
describes the essential computational challenges of 3G LTE
receivers is clarified and estimates of area, power, and interprocessor communication buffer requirements are presented
