Abstract
Methods and systems for filtering and enhancing the uplink reception sensitivity of OFDMA hybrid point to multipoint communication systems, including the steps of: determining transmission synchronization and bandwidth allocation for a plurality of wireless clients; communicating with the wireless clients via a plurality of hybrid converters connected to a shared signal distribution line, by using a wireless point to multi point centralized synchronizing communication controller and an OFDMA modulation; receiving wireless upload transmission by using the hybrid converters; and blocking non-information carrying sub-carriers, received by at least one of the hybrid converters, before superpositioning the received wireless upload transmissions on the shared signal distribution line.
