Diversity

Switching and detection at beginning of Receive.

Equalizer

Proprietary architecture, active only in 5.5Mbps and 11Mbps CCK modes. For multipath cancellation, the RF3000

defines the path with the largest magnitude as the main path and all others as secondary paths. The RF3000 equalizer

can cancel the two most significant secondary paths. these can either be two (2) post-cursor, echo paths, or they can be

one (1) post-cursor and one (1) pre-cursor paths. Pre-cursor delay can be up to one-quarter symbol period. Post-cursor

delay can be up to one (1) symbol period. The magnitude of cancelled multipaths up to -3dBc, normalized to the main

path.
