In this paper, a new architecture called Multi-Engine is proposed for W-CDMA baseband LSI. Multi-Engine architecture processes multiple channels at the base station by time-multiplexing. By processing at high speed such as 200 MHz, more than 10 channels can be accommodated in 1 LSI. The engines are controlled by software programs, allowing more flexibility to correspond to several modes of IMT-2000 standard. We have evaluated its effect by designing Multi-Engine on FPGA, and completed its software for the W-CDMA scheme.

New transmitter architecture employing EER (envelope elimination and restoration) method is proposed for mobile terminals. The effectiveness of the proposed architecture is evaluated by power efficiency estimation using theoretical models. The results showed its potential to gain three times higher average power efficiency as compared to that of conventional linear amplification architecture in WLAN (IEEE 802.11a) system. It accounts for 40% reduction in power dissipation. Intermodulation distortion of EER method is also evaluated. System parameters are fitted to the specifications of W-CDMA and WLAN.
