chip 1. In computer hardware, a miniaturized integrated electronic circuit etched on a tiny wafer of silicon. See also electronic, hardware, integrated circuit, and silicon. 2. In spread spectrum (SS) radio, a random pseudonoise (PN) code symbol. A sequence of chips, each of which has a much shorter duration than an information bit, are used to modulate the bits. The IEEE 802.11b standard for wireless LANs (WLANs), for example specifies Barker code at transmission rates of 1 Mbps and 2 Mbps, and complementary code keying (CCK) at 5.5 Mbps and 11 Mbps. Both Barker code and CCK code data bits into chips to form symbols prior to transmission. See also Barker code, CCK, code, DSSS, FHSS, SS, and symbol. |
