cdma2000ForwardReferenceChannels

(To be removed) Define cdma2000 forward reference channel

cdma2000ForwardReferenceChannels will be removed in a future release. (since R2026a)

Syntax

cfg = cdma2000ForwardReferenceChannels(wv)

cfg = cdma2000ForwardReferenceChannels(wv,numchips)

cfg = cdma2000ForwardReferenceChannels(BSTM-RC,numchips,P,M)

cfg = cdma2000ForwardReferenceChannels(traffic,numchips,F-SCH-SPEC)

Description

cfg = cdma2000ForwardReferenceChannels(wv) returns a structure, cfg, that defines the cdma2000^® forward link parameters given the input waveform identifier, wv. To generate a forward link reference channel waveform, pass this structure to the cdma2000ForwardWaveformGenerator function.

For all syntaxes, cdma2000ForwardReferenceChannels creates a configuration structure that is compliant with the cdma2000 physical layer specification [1].

cfg = cdma2000ForwardReferenceChannels(wv,numchips) specifies the number of chips to generate.

cfg = cdma2000ForwardReferenceChannels(BSTM-RC,numchips,P,M) returns the data structure for the BSTM-RC waveform identifiers, given the total traffic channel power, P, and the number of traffic channels, M. For more information on base station testing, see Table 6.5.2-1 of [2].

cfg = cdma2000ForwardReferenceChannels(traffic,numchips,F-SCH-SPEC) returns the data structure for the specified traffic channel, traffic, and the forward supplemental channel (F-SCH) and frame length combination, F-SCH-SPEC. If omitted, F-SCH-SPEC has a default value of the lowest F-SCH data rate allowable for a 20 ms frame length, given the radio configuration specified by traffic.

EnableCoding	'On' | 'Off'	Enable or disable channel coding
DataSource	Cell array: {'PN Type', RN Seed} or binary vector. Standard PN sequence options are 'PN9', 'PN15', 'PN23', 'PN9-ITU', and 'PN11'.	Data source. Specify a standard PN sequence with a random number seed or a custom vector.

FSCH Substructure

Include the FSCH substructure in the cfg structure to configure the forward supplemental channel (F-SCH). The FSCH substructure contains these fields.

Parameter Field	Values	Description
Enable	'On' | 'Off'	Enable or disable the channel
Power	Real scalar	Relative channel power (dB)
RadioConfiguration	'RC3' | 'RC4' | 'RC5' | 'RC6' | 'RC7' | 'RC8' | 'RC9'	Radio configuration channel
DataRate	1200 | 1350 | 1500 | 1800 | 2400 | 2700 | 3600 | 4800 | 7200 | 9600 | 14400 | 19200 | 28800 | 38400 | 57600 | 76800 | 115200 | 153600 | 230400 | 307200	Data rate (bps)
FrameLength	20 | 40 | 80	Frame length (ms)
CodingType	'Conv' | 'Turbo'	Channel coding type, convolutional or turbo
WalshCode	Nonnegative integer scalar such that 0 ≤ WalshCode ≤ 255	Walsh code number
LongCodeMask	Positive scalar integer	Long code identifier
EnableQOF	'On' | 'Off'	Enable QOF spreading
EnableCoding	'On' | 'Off'	Enable or disable channel coding
DataSource	Cell array: {'PN Type', RN Seed} or binary vector. Standard PN sequence options are 'PN9', 'PN15', 'PN23', 'PN9-ITU', and 'PN11'.	Data source. Specify a standard PN sequence with a random number seed or a custom vector.

FOCNS Substructure

Include the FOCNS substructure in the cfg structure to configure orthogonal channel noise source information. The FOCNS substructure contains these fields.

Parameter Field	Values	Description
Enable	'On' | 'Off'	Enable or disable the channel
Power	Real scalar	Relative channel power (dB)
WalshLength	64 | 128 | 256	Walsh code length
WalshCode	Nonnegative integer scalar such that 0 ≤ WalshCode ≤ WalshLength – 1	Walsh code number
