用灰色GM(1,1)模型对陕西省GDP 做预测
本文先用灰色GM(1,1)模型对陕西省GDP 做预测, 经过检验, 再用此模型确定另外一些未知指标, 最后通过确定的这些指标用
灰色GM(1,N)模型作预测, 通过比较总结两种模型各自的特点, 从而科学的指导陕西省经济发展,国内生产总值预测模型具有重要的现实意
义。
(This article first gray GM (1,1) models do forecast GDP of Shaanxi province, on examination, then this model to determine other unknown targets, and finally through the identification of these indicators of gray GM (1, N) model for prediction, by Comparison of two models summarize the characteristics of their own, so the guidance of scientific economic development in Shaanxi Province, China' s GDP forecast model has important practical significance.)

A multi-band orthogonal frequency division multiplexing (OFDM) ultra wideband (UWB) system
is being considered for the IEEE 802.15.3a wireless personal area networks. An enhancement to this system,
named pulsed-OFDM, has been proposed to reduce the complexity and power consumption of the transceiver
without sacrificing performance. In this paper, we describe a detailed implementation of a pulsed-OFDM
transceiver.
