Gitlin Richard Dennis, I Chih Lin: Code division multiple access system providing variable data rate access to a user.. At & T, November 15, 1995: EP0682423-A2 (83 worldwide citation)

A multi-code code division multiple access system allows a user at a radio transmitter unit to dynamically change its source data bit rate. In response to a user input selecting one of said plurality of source bit rates, an adjustable coding means in the transmitter spreads and transmits the user's ...

Huang Howard C, Ten Brink Stephan, I Chih Lin, Vannucci Giovanni: Pilot interference cancellation for a coherent wireless code division multiple access receiver. Lucent Technologies, November 4, 1998: EP0876002-A2 (20 worldwide citation)

A Code-Division Multiple Access (CDMA) receiver is disclosed which removes the pilot signal from the received signal. The pilot signal is defined by its multipath parameters (amplitudes, phase shift and delays) and its signature sequence. Since this information is known at the user's receiver termin ...

I Chih Lin, Sabnani Krishan Kumar: Method and apparatus for controlling the transmission power of different types of wireless devices in a cdma system.. At & T, November 2, 1995: EP0680159-A2 (17 worldwide citation)

The invention relates to the use of CDMA techniques. Data signals to be transmitted from a plurality of wireless devices (172,174,176,178,180) are spread across a common bandwidth. The data signals are received (via 114) by a base station (110) as a composite spread signal. The base station partiall ...
