What does the following expression indicates?

23 Views Asked by At

In my research work I came across the following representation:

Let $B(m)$ be the transmitted symbols, $B(m)$ $\in${-1,1}, for $m=1,2,...,1000$.

My query is what does above statement indicates.

As per my understanding it is indicating that $B(m)$ have values either -1 or 1 and in total the $B$ will be a vector of dimension 1 \times 1000.

Please comment if my understanding is correct and please let me know the mistake if my understanding is wrong.

Any help in this regard will be highly appreciated.
