Hello Joan,
I guess There is no simple answer. Please read paper for Mica2 Dongjin Son, Bhaskar Krishnamachari, John Heidemann Experimental Analysis of Concurrent Packet Transmissions in Low-PowerWireless Networks http://www-scf.usc.edu/~dongjins/paper/ISI-TR609-SonKrishnamachariHeidemann. pdf Regards, Aleksandr wbr, Sadkov Aleksandr [EMAIL PROTECTED] www.sumkino.com www.wl.unn.ru _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joan Cortes Sent: Friday, August 10, 2007 6:14 PM To: [email protected] Subject: [Tinyos-help] Intra-Channel Interference Rejection in CC2420 Hello, In the presence of two signals in the same channel where one of them is the desired transmission and the other one is interference (acting as channel noise), which power threshold (dB) between the desired and the interference signals is required by the CC2420 to be able to demodulate the desired signal? CC2420 datasheet gives values for adjacent and alternate channels but does not mention the case where more than one signal are received in the same frequency at some point. Considering that CC2420 uses DSSS it should be able to demodulate the desired signal even in presence of high channel noise. Thanks, Joan
