OFDM Tutorial Series: IEEE 802.16 Channel Models

The OFDM Tutorial Series goes in depth into the theory and implementation of OFDM wireless communication systems. Starting with the treatment of multipath fading channels, OFDM is introduced as a bandwidth efficient robust communication system for multipath fading channels. Using IEEE 802.11a as a basis, a full OFDM system is described in both theory and implementation. In particular, detailed description of acquisition including packet detection, timing synchronization, carrier frequency offset estimation and correction and channel estimation and equalization is presented along with implementation details.

In wireless communication, I wonder about what people are referring to when they use the term 'channel tap.',or 'delay taps' or 'doppler taps.' Can someone explain the term or provide me a definition? Any help will be appreciated!
