Abstract :
The performance of asynchronous Gaussian minimum shift keying (GMSK) direct-sequence spread-spectrum multiple-access (DS/SSMA) systems is evaluated using Pursley´s approach. Taking into consideration the interchip interference caused by the Gaussian lowpass filter, a closed-form expression for signal-to-noise (SNR) at the output of a coherent receiver is derived and then used for system analysis. A system optimisation or evaluation based on output SNR is efficiently carried out and compared with Monte-Carlo simulation.
