Channel impulse response (CIR) estimates are determined by time-interpolation for some of the data slots of the received signal which do not already include a pilot signal. For each of a sequence of symbols, a respective IFFT is performed on the pilot signals and interpolated channel estimates ...

Fig. 4: Multipath propagations, received signals, and channel response RSSI 的主要缺陷在于其无法捕捉多径效应。为了充分表征各个路径路径,无线传播信道建模为时间线性滤波器(temporal linear filter),也称为信道脉冲响应 (Channel Impulse Response,CIR)。在时不变(time-invariant)假设下,CIR h(\tau) 可表示为:...
小尺度参数(SSF):小尺度参数(SSPs)描述了CIR(Channel Impulse Response)的各个组成部分。这些组成部分是每个多径分量(MPC)的增益、延迟和角度。详细的解释可以在第3.3节中找到。 散射点位置(FBS / LBS):在已知发射机(TX)和接收机(RX)位置的路径延迟、增益和角度之后,当MT移动到不同的位置时,它们的值会更新。这...
UWB Channels can be measured by sounding the channel with pulses, and thereby obtain the impulse response. Multipath components have different waveforms depending on the type of transmitter and receiver antennas used and the angles of transmission and reception. A modified deconvolution technique is int...
A new algorithm estimating channel impulse response (CIR) length and noise variance for orthogonal frequency-division multiplexing (OFDM) systems with adaptive guard interval (GI) length is proposed. To estimate the CIR length and the noise variance, the different statistical characteristics of the add...

无线信道被建模为线性时间滤波器( linear temporal filter),以充分表征各个路径,称为信道脉冲响应( channel impulse response) (CIR)。在时不变假设下,CIR h(t) 表示为: $$ h(t)=\sum_{n=1}^N \alpha_n e^{-j \phi_n} \delta\left(t-\tau_n\right) $$ 其中 \alpha_n、\phi_n 和 \tau...
