Volume : II, Issue : VIII, September - 2012 Efficient Turbo Decoder Implementation For Software Defined Radios Rupesh Singh and Nidhi Singh Published By : Laxmi Book Publication Abstract : This paper provides a description of the turbo code used by the UMTS thirdgeneration
cellular standard, as standardized by the Third-Generation Partnership
Project (3GPP), and proposes an efficient decoder suitable for insertion into softwaredefined
radio or for use in computer simulations. Because the decoder is implemented in
software, rather than hardware, singleprecision floating-point arithmetic is assumed
and a variable number of decoder iterations is not only possible but desirable. The wellknown
log-MAP decoding algorithm with detailed analysis is proposed and the
simulation results are shown. Keywords : Article : Cite This Article : Rupesh Singh and Nidhi Singh, (2012). Efficient Turbo Decoder Implementation For Software Defined Radios.
