sequential code acquisition, maximum likelihood estimate (MLE), Bessel function.


In this paper, we consider the noncoherent code acquisition problem using sequential schemes. Since code acquisition schemes using the maximum likelihood estimate usually require a high level of computational complexity, simpli fied schemes are proposed and analyzed based on approx imations. The performance of the simplified and original code acquisition schemes are compared in additive white Gaussian noise and slowly-varying fading channels. Nu merical results show that the proposed schemes have essen tially the same performance as the original schemes while allowing simpler structures.
