Universal QAM/PSK modulator |
| Product code: CMS0004 |
|
Our universal QAM/PSK modulator core is aimed at broadband point-to-point and point-to-multipoint applications and supports QAM orders from 2 (BPSK) to 256.
It is compatible with the IEEE 802.16.x wireless MAN-SC and 802.15.3 wireless PAN Standards, and provides a comprehensive range of synthesis options to allow optimal trade-off between gate-count and feature set.
Integrates with Commsonics QAM Demodulator(CMS0006), Reed-Solomon(CMS0013) and Viterbi(CMS0002) cores to form a complete broadband Modem.
