Apart from adapting models by using noisy training material, the research area of model adaptation also covers 12 EURASIP ... dif- ferent training strategies: training on clean data, mismatched conditions training, and matched conditions training. Here, mismatched conditions training denotes the case when train...

In this paper, the two variants of B-IFDMA are considered, the joint- DFT B-IFDMA and the added-signal B-IFDMA, and compared in terms of ... spreading factor. In this approach, although the used spreading sequences contain no randomness, the authors introduce randomness by assuming that each of the Q sequences can be assigned...
