Thus, six bits of the original information sequence using QPSK 3/4 were transmitted in four time slots, and using QAM16 1/2 - in three, this demonstrates the QAM16 1/2 modulation code scheme advantage in channel and information rate. The high modulation code schemes using can improve the communication channel performance by increasing the throughput, however, as it is shown in the online course, the high modulation code schemes using is possible only for radio channels with a large link margin.
In the R5000 family InfiLINK 2x2, InfiMAN 2x2, InfiLINK Evolution and InfiMAN Evolutionfamilies devices, the modulation code scheme type is shown as a bitrate, in the InfiLINK XG and InfiLINK XG 1000 families devices, MCS itself is displayed. In In order to eliminate confusions, in the document below the MCS (modulation code scheme) index will be used. The The correspondence between modulation and index is shown in the table below.
