Comparison between one and two branches DLL in a CDMA system

Presents the results of simulations performed with the tracking module of a CDMA system software simulator (COSSAP), considering a mobile indoors environment. The simulation has been done with the different parameters that have an influence in the performance of the system such as SNR, number of users, initial misalignment, drift between clocks (emission and reception) and pilot gains, analyzing the parameter effects until the DLL is unlocked. The authors show the results and conclude that the two branches DLL improves the performance with respect to the one branch DLL but increasing the computational cost. The obtained results are compared with the theoretical results.<
