ADAPTIVE CODED MODULATION ADDED TO WIRELESS DATA MODEM

摘要

CML Microcircuits recently announced that it added Adaptive Coded Modulation (ACM) capabilities to its CMX7164 multimode wireless data modem, QAM modulation suite. ACM features enable the modulation type and block format to change on the fly to select data block size, coding rate, and CRC size. Over-air commands enable a Tx host to select an optimum modulation type and coding per burst to suit application message size and link channel quality. They can also relax required Rx host parsing speed. SPI Thru-Port macros speed serial slave control for shorter Tx/Rx mode transitions.
