Analysis of DSSS performance under communication-jamming environment

To achieve Anti-Jamming protection, DSSS Systems spread the baseband data signal over a broad bandwidth from the received signals with power below the noise floor. However, the existence of the near-far problem in multiple access DSSS Systems supports the notion that these signals can also be jammed though in normal case the detection of the DSSS Signals is difficult. The near-far problem is created by one signal (DSSS or otherwise) being significantly stronger than a DSSS signal within the same bandwidth so that the receiver is swamped by the first signal itself, which is similar to communication jamming phenomenon. In this paper performance of DSSS System are analyzed and the results are presented under different jamming conditions.
