Antenna and frequency diversity receiving apparatus

摘要

To adjust an antenna and frequency diversity receiving apparatus comprising n antennas (A1-An) and using m receiving frequencies to the best antenna frequency combination each of the n antennas (A1-An) there is assigned an IF stage (Z1-Zn). A quality signal (Q1-Qnm) representing the receiving quality will be generated for each of the nxm possible antenna frequency combinations within the IF stages (Z1-Zn). A digital signal processor (DS) determines by comparing the best antenna frequency combination out of the nxm quality signals (Q1-Qnm). The selected antenna (A1) will be switched to the digital signal processor (DS) via a multiplex switch (M), and the assigned IF stage (Z1) is tuned to the determined receiving frequency.
