Abstract :
We have derived the PDF of the decision variable for an adaptive serial search PN code acquisition scheme in Nakagami-m fading environment which is better suited for modeling the urban multipath mobile radio communication channel. The detection and false alarm probabilities have also been derived. These can be used for the computation of mean and variance of acquisition time
