Basically, the contents of this paper are organized as follows: Firstly, it is interpreted that the technical identifications of higher education and economic growth and the relative theories such as human capital and new economic growth, which can make theatric basis for the further empirical study. After that, the paper is to construct a couple of index systems to depict higher education development and economic growth respectively. At the end of this paper, it will adopt the dynamic econometric models such as Granger causality test, co-integration test, VAR and VECM model, to evaluate the co-relations between the two systems. According to the empirical study, the paper comes to the conclusions as follows:(1) There really exists one-way causality between the economic growth and the higher education, i.e.

Due to the fact that the intercarrier spacing in OFDM is relatively small, OFDM transceivers are somewhat more sensitive to phase noise compared to single carrier transceivers. Thus this problem must be carefully considered in designing an OFDMbased system since an accurate prediction of the tolerable phase noise can allow designer to relax system specifications. According to spectrum theorem, two components of phase noise were analyzed: common phase error and intercarrier interference. On the basis of the analysis, the performance of OFDM was given for the case where phase noise has been added to the signal, and an optimal design criterion for OFDM parameters was proposed that allows to improve the phase noise error correcting capabilities in OFDM receiver.
