Some one could explain what is the purpose of
Single Antenna Interference Cancellation (SAIC)
Thank you very much2nd October 2008 at 13:42 #54010saicGuest
I should have look first in wiki, before asking this question as the answer is there:
It is now a well known fact that it is possible to cancel the interference at the mobile handset side by changing the baseband software without changing anything in the network side. SAIC-enabled mobiles can work in high interference levels. SAIC-enabled mobiles need even less transmit power from the network which in turn reduces the interference for non-SAIC mobiles. studies shows that with 100% SAIC mobile penetration a capacity gain of 60 to 80% is achievable. There are various approaches possible to have a SAIC-enabled phone:
1. Prefilter based baseband algorithms (2X complex than conventional receiver but gives 12-15 dB gain)
2. Constant Modulus based SAIC (simple but less gain and also it is not very robust)
3. Joint Detection (JD)2nd October 2008 at 13:49 #54011saicGuest
Is it long time that SAIC is implemented?
Broadly speaking, how do we know that this or this Handset, have a feature implemented on it?
When we buy a phone, how do we know, that this phone support a special feature?2nd October 2008 at 15:55 #54012pixGuest
this technology was discovered in 2002 / 2003, but i never was aware of it 🙂 thanks !
on internet, i’ve found some papers… including this one:
first one is about nokia, second about sony ericsson… i would say that SAIC is used in most phones today.
“To further the adoption and standardization of this new technology, SAIC will be adopted as a work item in 3GPP, an international standards organization developing 3G evolution for GSM and UMTS.”
I bet you can find SAIC in 3GPP… if that’s the case, it means that all phones today are SAIC (because they got to be 3GPP compliant).
