1. The problem statement, all variables and given/known data A wireless communications system can achieve a theoretical maximum data rate of 200 Mbps using 16-QAM modulation in a 10 MHz channel and using a single spatial stream. What data rate could theoretically be achieved if the same system used 256-QAM and 8 spatial streams in a 20 MHz channel? 2. Relevant equations -- 3. The attempt at a solution I tried to multiply the constellations by the number of channels (8) ... but I can not find and understand the correct formula ... Could you help me find and understand, the mechanism of the formula?
