DIVERSITY INDICATING METHOD IN GERAN/MUROS SYSTEMS

摘要

A diversity indication method in GERAN/MUROS system, includes the steps: after a user receives a diversity indication, it receives data from two sub-channels, and then carries out diversity combination; if the user does not receive diversity indications, users receive data from subchannel allocated to them. Using the method of this invention, we can carry out diversity indications in GERAN/MUROS system. In this way, users do not need to determine whether current frame is using diversity transmission in all sub-channels by carrying out autocorrelated operations over training sequences 26 bit long in each frame, and the users may demodulate information from another paired subchannel only when they receive diversity indications in subchannel allocated regularly to greatly reduce the user's complexity.
