N2 - In this paper, we propose a new type of window-based pseudonoise (PN) code acquisition scheme, which does not resort to the window threshold, as opposed to the conventional scheme. In particular, it is selecting one or more largest hypothesis energies rather than selecting single largest hypothesis energy subject to the window threshold per search window for verification. By performing the numerical analysis based on a flow graph approach in AWGN and Rician fading channels, we show that the proposed scheme outperforms the conventional one under a low pilot Ec/Io while maintaining the similar level of performances under medium and high pilot Ec/Io's.
