Abstract:
1. A communication method of coordinated multi-point transmission systems, comprising the steps of: selecting a Zadoff-Chu sequence as a primitive training sequence; generating a set of orthogonal training sequences according to the primitive training sequence gone through with a set of cyclic shifts; allocating the set of orthogonal training sequences to multiple involving base stations; transmitting multiple preamble signals corresponding to the set of orthogonal training sequences from multiple base stations to a user equipment (UE) by a coordinated multi-point (CoMP) transmission method; and receiving a mixture signal of the multiple preamble signals at the UE, wherein the multiple orthogonal training sequences comply with relations of and 2≦k≦K; wherein, and N is the length of the orthogonal training sequence,
