Abstract:Future mobile terminals become multi-mode communication systems. In order to handle different standards, we propose to perform baseband processing in heterogeneous reconfigurable hardware. Not only the baseband processing but also error decoding differs for every communication system. Therefore we implemented an adaptive Viterbi decoder in the coarse-grained MONTIUM architecture. The rate, constraint length and decision depth of the decoder can be adjusted to different communication systems. We showed that the flexibility in the coarsegrained reconfigurable architecture has an estimated cost of 24 times more energy consumption compared to a dedicated solution
