CM_decoder_TCHDATA
Channel decoder and de-interleaver for data channels and FACCH in
accordance with “GSM Rec. 05.03” The CMI values located in
TCH_CMI_BUFF are decoded. The decoded bits are stored in
SCRATCH_BUFF. The data channel decoder is selected by the call of
CM_DECODER_TCHDATA_INIT.
rxqual_ber (format 16-bit integer) reflects the estimated bit error rate at the
input of the channel decoder (hard decision assumed) multiplied by 4096.
bfi_facch is the bad frame indication:
bfi_facch = 0; the decoded FACCH message is OK
bfi_facch = 1; a parity error has been detected
bfi_facch = 2; a bad metric error has been detected
bfi_facch = 3; both parity
and
bad metric errors have been detected.
The facch_flag indications:
facch_flag = 0; indicates that no FACCH message has been received. In
this case facch_msg[12] contains zeros.
facch_flag = 1; indicates that a FACCH message has been decoded and is
returned into facch_msg[12].
The facch_msg[12] contains the 184 bits of the decoded FACCH message.
The bits are stored in a packed format with 16-bits per word and LSB first
order. Unused MSBs are set to zero.

The parameter data_service may be one of the following values:
data_service = 0; full-rate = 9.6 kbits/s
data_service = 1; full-rate = 4.8 kbits/s
data_service = 2; full-rate
≤
2.4 kbits/s
data_service = 3; half-rate = 4.8 kbits/s
data_service = 4; half-rate
≤
2.4 kbits/s.
