Reviewer 2 Report

This study investigates the challenges of concurrent space-time block coding and modulation identification for multi-user upstream broadcasts in SC-FDMA systems, and presents a joint modulation and STBC identification algorithm for multiuser uplink SC-FDMA transmissions. Several interesting results are presented in this paper. However, I have some suggestions.

 1.     This paper lists six contributions. But some listed contributions are not outstanding. For example, the sixth contribution is only a feature of the proposed algorithm.

2.     The second section is not well organized.

3.     It is difficult to understand proposed identification algorithm. The authors should present pseudocode-based description.
