Abstract: For the reception of binary pseudorandom signals under the influence of intentional interference we introduce a randomized decisive rule with a region of indistinguishability of received signals. It is established that for signals with base $n\le 2$ the constructed rule of the receiver provides an increase in noise resistance of the information transmission system in the class of interference with limited average power as compared to the Kotelnikov receiver. The obtained value of the guaranteed error probability improves the actual upper bound for this quantity.

Keywords: signal generation and reception algorithm, pseudorandom signal, intentional interference, randomized reception rule, guaranteed error probability.
