Abstract
Decision rules for detection of spread spectrum signals were investigated. For each decision rule, error and erasure probabilities were analyzed. The obtained data was used to plot PE vs Pe for constant signal-to-noise ratio (SNR). With the use of the probability of a word error curves the optimum threshold setting was found for a given SNR.
FSK (orthogonal signalling) and PSK (antipodal signalling) were considered for modulating the chips. When the PE vs Pe plots for FSK and PSK were compared, PSK performed better than FSK by a ratio of 6 dB.
Finally, analog and digital correlation of the received signals were also investigated. Compared to the performance of analog correlation, the system performance for digital correlation was worse by less than 1 dB.
