Abstract :
We explore the performance of switched beam systems (SBS) under conditions of angular, delay, and Doppler spread. We offer a derivation of the probability of selecting a given beam when validation is done using TDMA color codes. This result is then used to derive the average CIR for a SBS using the given validation process. We simulate the performance of SBS using maximum received signal strength indicator (RSSI) validation and compare it to that of the standard sector antenna system. Finally, we simulate the performance of the color code validation scheme as compared to the maximum RSSI scheme.
