IS-95 Simulation Code

Simulates 9.6 kbps IS-95 system in static environment.

Description

This packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate. The simulation is written for static channel and AWGN noise.

The packet include:
1) Packet Builder (Viterbi Encoding, Interleaver, PN generation)
2) Modulator (RRC filter)
3) Demodulator (Matched Filter, RAKE receiver)
4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder).

You should run "Simulation.m" function that include all modules.

Undefined variable 'ErrorsB1'

I don't know if I run it correctly, but I got no results, no figures as they supposed to have. I run "simulation.m". Please let me know what I missed to run this code. My Matlab version is 6.5, R13. Thanks a lot.

please send me a copy of ur code.It is seems to be useful for the technical people.

[Oliver McDonald]

Good Stuff. As usual,matlab is slow when simulating communications systems.

[prasad reddy]

i am CDMA RF engineer.can u please send me the code for this. this is very useful for me.

[Rajesh Reddy]

can u send me a copy of the code so that it wil be very helpful to my project

1> This sim does not model IS95 BTS down-link since only 1 mobiles signal is txted.
2> Ideally, it must transmit 64 channels (paging, sync, pilot & users)
3> Further it has some errors from the comm system point-of-view.
4> To author's credit it makes good use of matlab's matrix arithmetic capability

I am doing my M.E in NIT Rourkela .I am very interested to see the topic then only i can apply this method in my thesis

I've analyzed your m file. I's good enough. But, i have 1 quistion (may be because i don't know yet), for data rate 9.6 kbps and frame length 20 ms, we need 192 bit per frame. But, why you use 184 netto bit as data transmit eventhough finally you add 8 zero bit (K-1) to make 184 bit become 192 bit. What's the meaning of 184 netto bit and 8 zero bit addition ??? Why you don't use 192 bit directly ???

[Rustam Efendi]

One more, continued my opinion before. For IS-95, transmission rate is 1228800 or 1.2288 Mbps. But in your m file, it is 122880. Can you give me more explanation about it?
Thx Mr. Zilberman.

IT IS SO HELPFULL OF YOU TO POST IT HERE.
PLEASE CAN YOU SEND ME A MORE ROBUST CODE SHOWING IS-95 CDMA FORWARD AND REVERSE CHANNEL(INCLUDING CHANNEL MODELLING).
               THANK YOU.

[lefteris mixail]

very help the program.Can you tell me more information about is-95(cdmaone)... your opinion will be very helpfull..

[star capricon]

It's a great knowledgable file with good description

[amy nadia]

 i dont know how to run this source code. Would you help me, please

[hussein suleiman]

please i need the reverse link cdma2000 m-file simulation with rake receiver

[Tony Tank]

very good!!!!!

[nomi nom]

Can you send me uplink power control code for cdma........

[Muhammad Rizwan]

Hi, I want to know something if you can help.
I have spread the bits with walsh code then with PN code and added awgn noise to it. On receiving side when I multiplied this received signal with conjugate of PN code it was removed from bit .Now how can I remove the walsh function to gain actual original bits.

[vivek k]

hi this is very good code for understanding IS-95 CDMA system ...

[dan chang]

please i need the multiuser reverse link cdmaOne-Is95 m-file simulation with matched filter

[Md.Humayun Kabir]

hi, could you please send me m-file simulation for Pilot channel de-spreading in IS-95 cdma for acquisition.

[Parag Dighe]

I was browsing through "Simulation.m". I found that on line 84 you generated Tx Data as randn(). Should rand() [uniform random] be a better choice ?

[Loheswari]

Can U please the m code for reverse channel of IS-95?
