A method for shaping the spectrum of the signal output from access equipment and an access equipment. The method includes: obtaining the power spectral density PSDco-rt of the signal at remote module access equipment from central office access equipment, and dividing the spectrum of remote module access equipment into overlap spectrum part and non-overlap spectrum part according to PSDco-rt, then according to PSDco-rt determining the power spectral density of signal sent from the overlap spectrum part of RT, and obtaining the shaped spectrum. This method can automatically or manually set the spectrum of downlink signal at remote module access equipment, thereby maximize spectrum utilization rate of remote module. So present invention has better spectrum compatible ability, flexibility and transmission performance. |
