dc.description.abstract	One of the practical problems in deployment and operation of fourth (4G) and fifth generation (5G NR) cellular communication systems is the reduction of noise immunity of physical channels in real operating conditions. The technology of signal diversity re-ception based on the use of several receiving antennas is one of the effective solutions for counteracting signal fading and increas-ing immunity to noise and interference. The search for an effec-tive detector of the physical control channel with low computa-tional complexity and, as a result, low power consumption is an urgent problem of ensuring the required quality of subscriber service in the entire range of services provided in 4G and 5G NR communication systems. The presence of correlation between interference on the receiving antennas gives rise to the problem of false detection, which negatively affects the quality of service and the efficiency of using radio resources. A physical uplink control channel (PUCCH) detector is proposed in the paper under diver-sity reception conditions using the Cholesky decomposition (CHOL-detector). The conditions for detecting a PUCCH channel with a constant probability of false alarm independent of the characteristics of the propagation channel and interference are determined. A mathematical model of the CHOL-detector is im-plemented and studied. The results of numerical modeling demonstrated an improvement in the noise immunity of the pro-posed detector by more than 2 times compared to the minimum requirements of the standard 3GPP TS 36.104.	ru_RU
