SIGNAL COMBINATION METHOD, DEVICE AND SYSTEM HAVING DIFFERENT SYSTEM, SAME BAND AND ANTENNA SHARING

摘要

A method for signal combination includes: filtering a signal received from a base station antenna diversity port (70) according to a preset first passband range; filtering a signal received from a base station antenna main port (60) according to a preset second passband range; combining the filtered signal from the base station antenna diversity port (70) and the filtered signal from the base station antenna main port (60); and transmitting the combined signal through a main port (80).
