Multipath Delay Spread

 Simulcast Networks Aside, the Signal at the Antenna is Really

Multiple Reflected Signals with Random Delays

– Extent of problem varies with topography

 Delay Spread Causes Bit Errors Even When Signal is Strong

– Weak correlation with signal strength remains

– Line-of-sight paths tend to have lower delay spread

 Unlike Simulcast, the Delay Profile is Time-Varying

– Adaptive equalizers are effective tool

– No guarantee manufacturer is using one, however

 I.e., Performance is Implementation-Dependent

– And it is unlikely that the mfr. has tested for all possible

environments
