... interference/noise. In the simplest case, where the transmitters are not collaborating and only receivers cooperate, systems result in higher SINRs and lower BERs for a given transmit power. ... either X1 or X2 as interference/noise. Such systems have lower SINRs and higher BERs for a given transmit power. They also usually require F-, T-, or C- DMA schemes to reduce interference ... worst-case interference analysis, assuming transmit power constraints, guarantees an upper limit on the inter-cell CCI. However, the performance suffers from the limited degrees of freedom available,...
