Abstract: A truncated adaptive transmission method suitable for a CDMA(Code Division Multiple Access)/FDM(Frequency Division Multiplexing) method in a forward link is provided to realize better performance than an FH(Frequency Hopping)-DS(Direct Sequence) even when either an orthogonal signature sequence or a probability signature sequence is used by increasing desired signal strength while restraining interference of a different cell base station in case of several cells. A complex low band pass response of the mth sub-channel between the jth cell base station and a reference user, the first user of the 0th cell is expressed by a certain equation. In a forward link under the environment of several cells, a sub-channel gain is obtained by multiplying a path loss and frequency Rayleigh attenuation together. The attenuation gains of each sub-channel are independent but the path loss of each sub-channel is the same.
