Chip (CDMA)
From Wikipedia, the free encyclopedia
A chip is one symbol (data) or pulse of a direct-sequence spread spectrum code, such as a pseudo-noise code sequence used in a CDMA system. One chip is representing several bits.
The chip rate of a code is a is the number of pulses per second (chips per second) at which the code is transmitted (or received). The chip rate is a symbol rate (also known as baud rate or modulation rate) that is larger than the bit rate.
Frequency-division and time-division techniques are supplanted in some modern systems by code-division techniques, including CDMA.
[edit] What is CDMA?
CDMA is one kind of spread-spectrum modulation system.
[edit] CDMA mobile phone systems
CDMA is in use as one standard for mobile phone systems. This application was pioneered by Qualcomm.
