摘要：
In the paper we present performance of turbo codes with SOVA decoder in DSSS over non-white channels. It has been shown, that its performance is similar to this, achieved in AWGN. Moreover, in order to increase its performance a double-matched reception has been employed. Thereby, the structure of a receiver is now matched not only to the useful signal, as it is in all classical receivers, but also to non-white noise. In comparison with a single-matched detection the obtained gains reach a dozen or so dBs depending on the entropy of noise.
