DS CDMA rayleighchan

hi,

i write matlab code for ds-cdma system and using rayleighchan function , which is matlab built in function.

H = rayleighchan (ts,fd,[0 110 190 140]*10^-9,[0 -10 -20 -23])

my question is : how can i equilize the received signal to cancel the effect of channel? for example in OFDM system we can send a pilot bit to use it in receiver to make the channel estimation, so in cdma how we will do that?

best regards :)
