  • Scalable radio platform
    Patent number: 6091967
    Abstract: A scalable radio platform for wireless communication systems which interfaces with either user equipment or system equipment to allow system parameters to be modified such that users of different communication systems can communicate with each other and also allows a wireless communication system to adapt to changing radio conditions.
    Type: Grant
    Filed: April 30, 1997
    Date of Patent: July 18, 2000
    Assignee: Lucent Technologies Inc.
    Inventors: Jan P. Kruys, Didier J. R. van Nee
  • OFDM digital communications system using complementary codes
    Patent number: 5862182
    Abstract: The encoding/transmission of information in an OFDM system is enhanced by using complementary codes. The complementary codes, more particularly, are converted into phase vectors and the resulting phase vectors are then used to modulate respective carrier signals. The modulated result is then transmitted to a receiver which decodes the received signals to recover the encoded information.
    Type: Grant
    Filed: July 30, 1996
    Date of Patent: January 19, 1999
    Assignee: Lucent Technologies Inc.
    Inventors: Geert Arnout Awater, Adriaan Kamerman, Anjur Sundaresan Krishnakumar, Didier J. R. van Nee
  • Digital communications system using complementary codes and amplitude modulation
    Patent number: 5841813
    Abstract: The encoding/transmission of information in an OFDM system is enhanced by using complementary codes and different patterns of amplitude modulation representing respective data words. The complementary codes, more particularly, are converted into phase vectors and modulated by the selected pattern. The result is then used to modulate respective carrier signals. The modulated result is then transmitted to a receiver which decodes the received signals to recover the encoded information.
