Narrowing the passband of the phase-keyed signal receiver
V. V. Gorshenin, Alexey V. Kiselev
The paper is devoted to narrowing the passband in a radio receiver of phase-keyed signals. The narrowing is attained due to diminishing the coefficient of signal spectrum round-off by the reception channel. It is shown that in this case we can reach a considerable improvement of selectivity with respect to the neighboring channel, when the sensitivity and the intersymbol interference level are within allowable limits.
