What is the diversity reception? How can it be used to combat multipath?
What will be an ideal response?
Diversity reception: Two frequencies that are larger than the coherence
bandwidth and fade independently. This concept is used in diversity reception. Therefore, it is a radio reception in which a resultant signal is obtained by combining or selecting signals, from two or more independent sources. They are modulated with identical information-bearing signals. (i.e., multiple copies of same message are sent using different frequencies.) Combating with multipath: The signals are chosen such that the frequencies are larger than coherence bandwidth therefore their fading characteristics are independent at any given instant. This minimizes effects of correlated fading.

In LEED v4 sustainability rating system, a building may earn a maximum of 110 points. Of these 110 points, 99 points may be earned from the impact of a building on six environmental impact categories, which are: 1. Location and Transportation (LT); 2. Sustainable Sites (SS); 3. Water Efficiency (WE); 4. Energy and Atmosphere (EA); 5. Materials and Resources (MR); and 6. Indoor Environmental
Quality (EQ). Each category has been assigned points, so that the sum total of points in all six categories is 99. The number of points assigned to a category gives its relative importance to sustainability of the building. The MR category deals with the impact of materials used in the building on the environment. How many points are assigned to this category? What will be an ideal response?
