Towards Software Defined Radios Using Coarse-Grained Reconfigurable Hardware

Mobile wireless terminals tend to become multimode wireless communication devices. Furthermore, these devices become adaptive. Heterogeneous reconfigurable hardware provides the flexibility, performance, and efficiency to enable the implementation of these devices. The implementation of a wideband code division multiple access and an orthogonal frequency division multiplexing receiver using the same coarse-grained reconfigurable MONTIUM tile processor is discussed. Besides the baseband processing part of the receiver, the same reconfigurable processor has also been used to implement Viterbi and Turbo channel decoders.
