DIVERSITY RECEPTION WITH ADDITION IN ANTENNAS

摘要

communications engineering. SUBSTANCE: circuit arrangement of antenna is designed to raise sensitivity of base station by using several antennas each servicing different or partially covered areas of larger cell; each antenna is differently positioned. Receiver of each antenna receives signals transmitted by mobile stations. Correctors installed in all receivers function to correct signals received. Adder integrates signals received by different antennas to obtain estimate of signal transmitted. EFFECT: enhanced sensitivity. 8 cl, 7 dwg
