<P>PROBLEM TO BE SOLVED: To provide a method and apparatus for channel estimation in a system employing different transmission protocols such as a broadcast/multicast protocol and a unicast protocol. <P>SOLUTION: When pilots of adjacent slots are used for channel estimation, quality of channel estimation deteriorates significantly. To solve the problem, it is determined whether a first time slot (multicast slot) of one transmission protocol is adjacent to a second time slot (unicast slot) of another transmission protocol (510); a symbol of an edge slot is determined (520); the pilot power and/or the number of pilot sub-carriers is increased (530); and channel estimation is performed using the edge symbol (540). <P>COPYRIGHT: (C)2013,JPO&INPIT |
