N2 - In this paper, we propose a generalized version of window-based pseudonoise (PN) code acquisition scheme selecting one or more largest hypothesis energies rather than selecting the single largest one per search window for verification. By performing the numerical analysis based on the flow graph approach, we show that our proposed scheme selecting the plural largest hypothesis energies outperforms the conventional one in both the AWGN and Rayleigh fading channels. Furthermore, it is shown that we can obtain the optimum window size robust to the variation of the pilot Ec/Io with our proposed scheme.
