In this paper, acquisition performance with adaptive pre-filtering is analyzed for a "coherent Paralperformance in a mobile fading channel. Under severe multiDath fading conditions. the P N code acauisition is difficult Y le1 matched-filter (MF) acquisition scheme with a reference filter (RF) in a multipath fading channel. Adaptive prefilterina is emoloved to reduce the effect of severe multipath due to delay spread and signal power degradation. n this paper, acquisition performance with adaptive pre0 1 " .. . . -. ... fading. From the numerical results, i t is shown that adapfiltering is analyzed for a noncoherent parallel matchedfilter (MF) acquisition scheme with an RF in a multipath fading channel. The performance measure is evaluated in tive pre-filtering and reference filtering improve acquisition performance in multipath fading environments.

In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...

In this paper, we propose smart step closed-loop power control (SSPC) algorithm and base station assignment based on minimizing the transmitter power (BSAMTP) technique in a direct sequence-code division multiple access (DS-CDMA) receiver in the presence of frequency-selective Rayleigh fading. This receiver consists of three stages. In the first stage, with conjugate gradient (CG) adaptive ...

This paper compares the mean acquisition time (MAT) performance of two serial search acquisition schemes over frequency-selective multipath Rayleigh fading channels. Both the conventional cell-by-cell detection and the novel joint two-cell detection are characterized. In contrast to the majority of published results considering only one correct timing state ( 1 cell) in the uncertainty region o...

In this paper, we investigate the issue of pseudo noise (PN) code acquisition in single-carrier and multicarrier (MC) direct-sequence code-division multiple-access (DS-CDMA) systems, when the channel is modeled by frequency-selective Nakagamifading. The PN code acquisition performance of single-carrier and MC DS-CDMA systems is analyzed and compared when communicating over Nakagamifading channe...
