Abstract

A short PN code generating device in a mobile communication network having an Nx CDMA communication system performing spreading at an Nx chip rate using a short PN code of chip length Nx2k and a 1x CDMA communication system performing spreading at a 1x chip rate using a short PN code of chip length 2k. The device generates a short PN code such that the Nx CDMA communication system can distinguish at least the same number of base stations as the 1x CDMA communication system can distinguish. The device includes a sequence generator for generating an m-sequence having a chip length longer than the chip length Nx2k to output an I-component short PN code; and a short PN code generator for switching the generated m-sequence at predetermined chip periods to alternately output the m-sequence as an I-component short PN code and a Qcomponent short PN code.
