I would like to know what is the name of this math font? The math font is giving in three different pictures below. I zoomed-in in the original pdf and I took the pictures.

Figure 1


Figure 2


Figure 3


I read this survey about math font provided here. The previous texSE link seems to be similar to this font but there is some differences for example in the sum symbol $\sum$.

It seems to me that the font is \usepackage{mathptmx} or \usepackage{mathtime} or \usepackage[varg]{txfonts}. I tried them but I found some dissimilarities in the formulas like for the $\alpha$ and the $g_{m,n}$.

It would be grateful if some one help me to figure what is this math font?

Is this what you are after?

enter image description here

\documentclass[12pt,a4paper]{article}
\renewcommand{\rmdefault}{ptm}
\usepackage[lite]{mtpro2}
\begin{document}

\[g_{m,n} = \Gamma_m h_{m,n} d_{m,n}^{-\alpha_m},\]
\[R_{m,n} = b_{m,n} \log_2(1+\mathit{SNR}_{m,n}), \forall m,n\]
\[R_n = \sum_{m=1}^M R_{m,n} \log_2 \left( 1+\frac{p_{m,n}g_{m,n}}{b_{m,n}N_0}\right),\forall n\]
\[C1: \sum_{n=1}^N b_{m,n} \leq W_m, \forall m,\]
\[C3: \sum_{m=1}^M R_{m,n} \geq R_n^{\min}, \forall n,\]

\end{document}

Then, you might try mtpro2 package. It is a commercial package, but fortunately, there is a lite version which you can download from their site here. The lite version lacks some features like bold Greek symbols, ultra-thick operators, mathbb, etc. But if you are interested, you might afford buying the full package.

How about trying some free font newtxtext and newtxmath:

\documentclass[12pt,a4paper]{article}
\usepackage{newtxtext,newtxmath}
\begin{document}

\[g_{m,n} = \Gamma_m h_{m,n} d_{m,n}^{-\alpha_m},\]
\[R_{m,n} = b_{m,n} \log_2(1+\mathit{SNR}_{m,n}), \forall m,n\]
\[R_n = \sum_{m=1}^M R_{m,n} \log_2 \left( 1+\frac{p_{m,n}g_{m,n}}{b_{m,n}N_0}\right),\forall n\]
\[C1: \sum_{n=1}^N b_{m,n} \leq W_m, \forall m,\]
\[C3: \sum_{m=1}^M R_{m,n} \geq R_n^{\min}, \forall n,\]

\end{document}
