Multiframe output data generation

[real-time mode]

 

Coding scheme

Full-rate speech [TCH/FS]

[Option 402]

 

 

CS-1, CS-4

 

 

 

 

 

 

Data

PN9 or PN15

 

 

 

The selected data sequence is coded continuously

 

 

 

across the RLC data block as per ETSI TS 100 909, 3GPP

 

 

 

TS 05.03, V8.9.0, 2000-11 [release 1999]

 

 

 

An independent version of the selected data sequence

 

 

 

is coded across the MAC header.

 

 

 

 

 

 

Frame structure

26-frame multi-frame structure as per ETSI

 

 

 

GSM, 05.01 version 6.1.1 [1998-07].

 

 

 

[Coding is done on frames 0-11, 13-24, of the multi-frame.

 

 

 

Frame 25 is idle [RF blanked].]

 

 

 

 

 

 

Adjacent timeslots

 

 

 

Data

PN9, PN15 coded as per ETSI TS 100 909, 3GPP

 

 

 

TS 05.03, V8.9.0, 2000-11 [release 1999].

 

 

Frame structure

26-frame multi-frame structure as per ETSI GSM,

 

 

 

5.01 version 6.1.1 [1998-07].

 

 

 

 

Multiframe measurements1

 

 

 

GSM measurement modes

 

 

 

Static sensitivity

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.]

 

 

Sensitivity search

Automatically finds the input level [sensitivity] that causes

 

 

 

a user-specified RBER [normally 2%] for class II bits.

 

 

Maximum frame count 6,000,000 speech frames

 

 

 

 

 

 

GSM measurement results
