  • Automatic delay calibration and tracking for ultra-wideband antenna array
    Patent number: 7925251
    Abstract: A method for determining changes in internal delays of RF units, the RF units including a plurality of receivers and transmitters. The method includes providing initial direct signals' time of arrivals of the RF units initial internal delays of the RF units. Following this, each transmitter transmitting a direct signal, and the real-time direct signal's time of arrivals of the RF units, are measured. Then, changes in internal delays of the RF units are calculated based on the real-time direct signals' time of arrivals and initial direct signals' time of arrivals. And finally, real-time internal delays of the RF units are calculated based on the changes in internal delays and the initial internal delays of the RF units.

  • Preamble generator for a multiband OFDM transceiver
    Patent number: 7411898
    Abstract: Preamble generator for a multiband frequency division multplexing (OFDM) tranceiver of a wireless personal area network (WPAN) being switchable between a time frequency interleaving (TFI)-mode wherein data packets are transmitted by said transceiver in different frequency bands according to a predetermined frequency hopping pattern and a fixed frequency interleaving (FFI) mode wherein data packets are transmitted by the transceiver in at least one fixed frequency band, wherein said preamble generator scrambles in the fixed frequency interleaving (FFI) mode a predetermined preamble of the data packets by multiplying said preamble with a pseudo random data sequence to flatten a power spectrum of said preamble.
