Abstract A new algorithm of IF noise simulation for a multichannel direct spread-spectrum system is proposed. The influences between each channel of spread-spectrum signals are treated as noise in this algorithm. A new algorithm of proportional divisor that is suitable for the signals mixture of a multichannel spread-spectrum system is put forward based on this noise simulation algorithm. This algorithm is applied successfully to an IF signal simulator of one multichannel direct spread-spectrum system. The experimental results show that the precision of IF signal generated by this algorithm is much better than it generated in traditional way.
