Modified Rectangular Patch Antenna for WLAN and WiMAX Application

A novel energy efficient two‐dimensional pilot muting mechanism for non‐stationary channel fading environment

“…The achievable data rate of RBs in pilot aided‐communication can be approximated by [9]: $$$$\begin{equation} \begin{aligned} C_\text{s}&=S(D_\text{p})\log (1+\overline{\gamma }) \end{aligned} \end{equation}$$$$where $$S(D^\text{p})$$ is the instantaneous spectrum utilization function of RBs[4] and can described as: $$$$\begin{equation} \begin{aligned} S(D_\text{p})=(N_{\text{sub}}(N_{\text{sym}}-N_{\text{ctrl}})-N_\text{T}D_\text{p})/(N_{\text{sub}}(N_{\text{sym}}-N_{\text{ctrl}})) \end{aligned} \end{equation}$$$$where $$N_\text{T}$$ is the number of transmitter antennas, $$\overline{\gamma }$$ is the post‐equalization signal‐to‐interference and noise ratio (SINR) of RBs and can be expressed as [4, 10]: …”
