WebIn "802.11b/g DSSS/CCK/PBCC" mode, the VSA will support automatic detection, demodulation, and de-scrambling of the four mandatory 802.11b signal formats (1, 2, 5.5, … Web802.11b also adds 5.5 Mbps and 11 Mbps data rates. These data rates are achieved by using CCK (Complementary Code Keying). CCK applies a code sequence of 8 bits that is calculated depending on the incoming data. The outcome is that by increasing the modulation efficiency, the data rate is increased although the bandwidth is maintained. 3d house design software free online WebIn "802.11b/g DSSS/CCK/PBCC" mode, the VSA will support automatic detection, demodulation, and de-scrambling of the four mandatory 802.11b signal formats (1, 2, 5.5, and 11 Mb/sec), as well as detection and demodulation of the optional 802.11b and 802.11g PBCC formats. The VSA will detect but not demodulate the optional DSSS-OFDM format … WebSpecifically, we used the phase shift keying modulation (PSK) and Complementary Code Keying modulation (CCK) . In the PSK modulation, the phase of the carrier varies, while the amplitude of the carrier remains constant. ...
