[N.sub.R] = [N.sub.D] = 2, [[rho].sub.1] = [[rho].sub.2], E{[[gamma].sub.R]} = E{[[gamma].sub.D]}, [[rho].sub.R[1]/[[rho].sub.R,[2]] [[rho].sub.D,[1]]/[[rho].sub.D[2]] =1, and the signal-to-interference ratio (SIR) is defined as [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII].
The strength of the interference is studied using signal-to-interference ratio (SIR) [rho] = [[bar.[gamma]].sub.1]/ [[bar.[gamma]].sub.INF] .
Such devices thereby adjust their signal-to-interference ratio (whenever the oven is turned on) and could possibly remain immune from adverse effects of packet-losses due to the EMI under discussion.
In fading environments as cellular systems, where the level of the cochannel interference is sufficiently high compared to thermal noise, SSC receiver adheres to one branch as long as the signal-to-interference ratio (SIR) is greater than a specific threshold.
