SCM stands for Spread Spectrum Code Multiple Access. It is a multiple access technique used in wireless communication systems. SCM allows multiple users to share the same frequency band without interfering with each other. This is done by spreading the user’s signal over a wide range of frequencies using a pseudorandom code. The receiver can then recover the original signal by despreading it using the same code.
The answer to the question is: A. Maximum receiver power level for a particular user.
SCM is a power-controlled multiple access technique. This means that the receiver power level is controlled to ensure that the received signal is at a comfortable level for the receiver. The maximum receiver power level is the maximum power that the receiver can handle without being damaged.
The other options are incorrect because they do not describe the purpose of SCM. Option B is the maximum transmitter power level, which is not relevant to SCM. Option C is the minimum receiver power level, which is not relevant to SCM. Option D is the minimum transmitter power level, which is not relevant to SCM.
