HHTtransformanalysisofpressurepulsewavesignal
本文采用的是先对脉搏波进行经验模态分解，产生一组内在的模函数，每一种模态对应一种物理状态，之后使用ＨＴ得出瞬时的频率和振幅，进而得到边际谱(In this paper, is the first of the pulse wave empirical mode decomposition, resulting in a set of intrinsic mode function, each mode corresponds to a physical state, followed by the use of HT derived instantaneous frequency and amplitude, and thus to be marginal spectrum)

modified_sinr
The signal received by a user over the forward link in such a high data rate system contains interference from the neighboring base stations. we note that the strength of this interference is a function of the network load in the neighboring cells. we obtain an expression for the received SINR (Signal to Interference and Noise Ratio) as a function of the traffic load in the interfering cells. Using this result, we propose an improvement to the SINR estimation scheme that is implemented in the current cellular data network. The proposed scheme provides a more accurate estimate of the user SINR by taking better account of the contribution of inter-cell interference. It builds on top of the current SINR measurement scheme by using a combination of pilot measurement and traffic load measurement
