The chip rate (chips per second) of the spread code is defined as the number of pulses per second.
To lower the PSD of a waveform, a Pseudo-Noise (PN) Code of the appropriate chip rate must be XORed with the transmitted data.
[T.sub.c] is the inverse of the chip rate. The chip rate is nominally 2 Mchip/s which is 32 times the symbol rate [19].
The chip rate for WCDMA is 3.84 megachips per second (Mc/s).
The reference design includes all baseband processing, including sample rate, chip rate and symbol rate operations, as well as MAC-hs scheduler, operations and management (OAM) functionality and protocol termination.
