Inducing desired frame error patterns and rates in a CDMA wireless
communication channel. The induced frame errors may be used to test a
digital radio receiver's behavior in the presence of frame errors.
Preferred methods include providing a carrier signal having at least one
data channel, where the data channel has a plurality of data frames;
generating discrete noise bursts of radio frequency noise, where the
noise bursts have a duration characteristic and an interval
characteristic; and, combining the noise bursts and the carrier signal to
induce a desired frame error characteristic.
