cdma2000ForwardReferenceChannels

Define cdma2000 forward reference channel

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].

example

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

example

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].

example

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}`, binary vector, or a paging message character vector. Standard PN types are `'PN9'`, `'PN15'`, `'PN23'`, `'PN9-ITU'`, and `'PN11'`.

Specify a standard PN sequence with a random number seed, a binary vector, or one of three paging messages. For a description of paging message contents see footnote 1.
When the `DataSource` enumeration specifies one of the paging message options, simulated paging message data is used as input to the F-PCH physical channel: `'PagingMessage1'` — Streams a 7680 bit sequence (800 ms at fullrate) of paging message contents onto the channel that includes the General Page Message, the CDMA Channel List Message, the Extended System Parameter Message, the Extended Neighbor List Message, the System Parameter Message, and the Access Parameter Message. The paging message repeats these messages in a nonsequential pattern. `'PagingMessage2'` — Streams a 2304 bit sequence (240 ms at fullrate) of paging message contents onto the channel that includes a truncated version of the full `'PagingMessage1'` content. `'PagingMessage3'` — Streams an 864 bit sequence (90 ms at fullrate) of paging message contents onto the channel that includes the Neighbor List Message, the CDMA Channel List Message, the General Page Message, the System Parameter Message, and the Access Parameter Message. The paging message repeats these messages in a sequential pattern. For more information on the F-PCH contents, refer to 3GPP2 C.S0004, Table 3.1.2.3.1.1.2–1.
