Abstract
The software radio has the advantages of flexibility, low cost and multimode ability, but the major disadvantage is the slower speed. To increase the speed of PC-based software DVB-T receiver, we need implement the baseband signal processing algorithms much faster. In this thesis, we discuss faster implementation of (1) 16QAM de-mapper to bits, (2) expanding_channel coefficient value in Viterbi decoder, and (3) inner de-interleaver and depuncturer. The speed of these three blocks is 6.64x, 0.57x and 0.88x faster.
