—This paper presents a low-power ASIC design for cell search in the wideband code-division multiple-access (W-CDMA) system. A low-complexity algorithm that is able to work satisfactorily under the effect of large frequency and clock errors is designed first. Then, a set of low-power measures are employed in the design of hardware architecture and circuits.(More)
—This paper proposes a complete cell-search solution for real-world handset operations in the wide-band code-division multiple-access system. Large-frequency and clock errors are induced at initial search due to an inaccuracy of crystal oscillators within handsets and could cause fatal performance degradation. In addition to a primary search algorithm for(More)
— We consider the downlink of a multiuser multi-input multi-output (MIMO) broadcast channel under a single cell structure. To study the achievable link coverage performance of zero-forcing beamforming (ZFB) and zero-forcing dirty-paper coding (ZF-DPC) when the channel state information (CSI) is available to the transmitter. First we develop analytical(More)
The rapid growth of the Internet has created a demand for the router that can process heavy traffic and achieve gigabit speed. Currently, the process of IP lookups is done in software and has become a major performance bottleneck for the router. In connection with this problem, many fast IP routing lookup mechanisms are proposed. But most of them focus on(More)
