Detection of impulse noise using unused spreading codes

The device for detecting the low level and high detection layer and a pulse detector in CDMA system, comprising is provided with a code comprising a computational the background-noise layer circuit. The circuit and calculates spread spectrum end of the middle and power with code to is provided with output each spread spectrum gap noise power. The circuit for outputting middle background power and calculates the averaging value in spread spectrum gap of. The comparator's and background noise power current spread spectrum and a power switch and a programmable threshold value to compare, and when surpassing the background noise power switch and first threshold value with a deletion indicating.
