Spread spectrum signals are a class of signals that primarily designed for use in digital

communication systems to overcome either intentional or unintentional interference.

$($i$)$ Consider a DSSS system and an FHSS system. Assume that the two systems

have the same chip rate. Let $M$ denote the number of frequencies in the FHSS

system. If we transmit the same message signal by the two systems, which one

will provide a higher processing gain $($PG$)?$ Explain your answer.
