cdma2000ForwardReferenceChannels

Define cdma2000 forward reference channel

Description

example

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.

The paging message repeats these messages in a nonsequential pattern.
