Looking for materials about Outage probability on digital microwave links

Please I need materials on Outage probability on digital microwave links. I am embarking a research on the topic

Dear Seyetronics:
Please read any good textbook on microwave communication. There are many causes of outages; link availability is the reverse term. In general, propagation loss due to precipitations, fading due to obstacles and differential phase causing clock interruption are the main ones.

There is a book Introduction to Wireless communication Systems by Rappaport with all the information you need. you can download it here
