After compiling, it gives this error

File ended while scanning use of \Gscale@box@dd.

and does not display the pdf output.

Brenda, there is an unpaired brace in 64QAM{{optional} so, to prevent the error when compiling the document, either make it 64QAM{{optional}} OR 64QAM{optional}, however, I suspect you intended the 'optional' to be inside standard brackets, as follows:

\documentclass{article}
\usepackage{graphicx}

Nicholas Hamilton has already explained your error, but I'd like to suggest to you some improvements.

In my opinion, your table could be clearer without all those rules (especially the vertical ones).

Moreover, you should use \centering, not the center environment within a table environment, see here: Should I use center or centering for figures and tables?.

Instead of resizing your table to fit the page, you could choose a smaller font (\small, \scriptsize, \tiny) and/or use tabularx.

Finally, I didn't know what your text means (hence I didn't change it), but I think you should have a look at siunitx package.

\documentclass{article}
\usepackage{booktabs}
\usepackage{tabularx}
\usepackage{makecell}
\renewcommand*{\arraystretch}{1.4}
\usepackage{graphicx}
\usepackage{caption}

\begin{document}
    \begin{table}[ht]
        \centering\small
        \caption{Specifications of LTE\label{tab:table1}}
            \begin{tabularx}{\linewidth}{lX} 
                \toprule

    Using siunitx is indeed recommended; for instance it would avoid errors such as “hr” instead of “h” and “MHZ” instead of “MHz”. – egreg Nov 24 '17 at 10:27
