Soviet Religious Policy in the Baltics under Khrushchev, 1957-1964

The Khrushchev era brought a policy of religious repression in response to a resurgence of religious adherence after WWII. But a close evaluation of archival sources reveals distinctive features to its implementation in the Baltics, compared with other parts of the USSR and with the Orthodox Church. The study richly describes the erosion of church institutional interests, such as maintenance of registered churches and clergy, legal and financial autonomy, publications and theological education. But having adapted to their national context, republic-level state officials often pursued the campaign disproportionately against non-national churches, such as Catholics and so-called sects, thereby provoking bureaucratic tensions with party hardliners, both in Moscow and at the republic level. Motivated by its heightened anti- Vatican stance, Moscow’s foreign policy opening—to the World Council of Churches, Lutheran World Federation, and the German churches—brought the Lutheran churches limited leverage against reluctant local and republic officials

Mitigation of spectral leakage for single carrier, block-processing cognitive radio receivers

Cognitive Radio (CR) is a multiuser, wireless communication concept that allows for a dynamic and adaptive assignment of spectral resources. The coexistence of multiple users, often transmitting at significantly different power levels, makes CR receivers vulnerable to spectral leakage caused by components’ nonlinearities and time-truncation of the processed signal records. In this work we propose a method for mitigating the latter with an adaptive choice of the length of the processing block size. With simulations we show that a significant leakage reduction that leads to receiver dynamic range improvement of around 10 dB can be achieved with the proposed method.
