RBER at user-specified power
level measured. (This is the
complete conformance test as
defined in pri-ETS 300 609-1
(GSM 11.21) version 4.12.0
(Dec 98), section 7.3.4.
Automatically finds the input level
(sensitivity) that causes a user
specified RBER (normally 2%)
for class II bits.
6,000,000 speech frames
Continuous PN9 or PN15
Sequence for raw BER
Continuous PN9 or PN15
Sequence on header and data
payload.
Fully coded MCS-5 and MCS-9;
channel coding provided on PN9
or PN15 for data payload. Coding
is done on frames 0 – 11, 13-24,
26-37, 39-50 on a 52 PDCH
multiframe. The selected signal
pattern is inserted continuously
across the full payload.
52-frame multiframe structure for
EDGE/EGPRS channel as per
ETSI GSM 05.01 release 99.
Frames 12, 25, 38 and 51 are
empty (no burst).
