what are the criteria to decide contiguous carriers?
the amount of spectrum that a mobile network operator owns, the amount of data you want to transmit, and a commercially-motivated decision by the network to combine multiple component carriers for you.
So, all in all, not a signal processing, but a system and spectrum utilization as well as a financial ...
The answer is Shannon's limit, which is given by:.
$C = B log_2 (1 + γ)$
where $C$ is the “capacity,” or maximum error-free data rate, $B$ is the bandwidth of the
channel, and $γ$ is the SNR (or SINR).
As received signal power increases, the Signal to Noise Ratio (SNR), $\gamma$, increases, since SNR is the ratio of signal power to the noise power. If $\...
