| 单词 | BPSK (Binary Phase Shift Keying) |
| 释义 | BPSK (Binary Phase Shift Keying) A unibit PSK modulation technique in which the continuous analog waveform is interrupted and restarted at the baseline with a 180° phase shift to indicate a change in value from a 1 bit to a 0 bit or from a 0 bit to a 1 bit. As examples, Wi-Fi5 (802.11a) wireless LAN (WLAN) standards specify BPSK at 6 Mbps, Personal Communications System (PCS) cellular radio specifies BPSK in the 800–900 MHz band, and ZigBee specifies BPSK in the 868 and 915 MHz bands. See Figure B-3. See also 802.11a, analog, cellular radio, Manchester coding, modulation, PCS, phase, PSK, unibit, waveform, Wi-Fi5, WLAN, and ZigBee. 74570c02.qxd 9/11/07 12:18 PM Page 67 |
