Patent number: 8958789Abstract: An optical medium, such as fiber, is tapped to provide an antenna port wherever radio service coverage is desired. Each antenna port is a bi-directional remote unit that receives a digital optical signal from a host unit and transforms the signal to a radio frequency signal for transmission by the remote unit. The remote unit receives radio frequency signals that are converted to digital signals and summed with signals from other remote units and converted to an optical signal for transmission to the host unit.Type: GrantFiled: March 24, 2003Date of Patent: February 17, 2015Assignee: ADC Telecommunications, Inc.Inventors: Donald R. Bauman, Philip M. Wala, Jeffrey O. Brennan

Patent number: 8437383Abstract: Systems and methods for digitally equalizing a signal in a distributed antenna system are provided. In one embodiment, a signal processing device within a distributed antenna system comprises a signal path within a signal processing board, the signal path having an uncompensated distortion function of G(?) with a system response represented by y(n); and a compensator coupled to the signal path, the compensator having a finite impulse response (FIR) filter with an impulse response function represented by H(?), the compensator having an FIR filter parameter vector {right arrow over (h)} determined from an estimated system response y(n) of the signal path to an input comb signal x(n), wherein y(n) is estimated from interpolated measured output responses of the signal path to a plurality of frequency sweep signal test inputs.Type: GrantFiled: March 5, 2012Date of Patent: May 7, 2013Assignee: ADC Telecommunications, Inc.Inventors: Bernard K. Wiwel, Jeffrey O. Brennan, Philip M. Wala, Jeffrey J. Cannon, Dean Zavadsky

Patent number: RE40564Abstract: A method and apparatus for sectorizing coverage of a cellular communications area includes providing a remote unit having microcell antenna units. Each microcell antenna unit is configured to cover a particular sector. The remote unit is connected to a sectorized base station unit which is connected to a mobile telecommunications switching office. Separate digitized streams representative of telephone signals received from the mobile telecommunications switching office are generated corresponding to the microcell antenna units and the separate digitized streams are multiplexed and transmitted to the remote unit. The remote unit demultiplexes the multiplexed digitized streams into the separate digitized streams corresponding to the microcell antenna units and the separate digitized streams are converted to RF signals for coverage of a particular sector by the corresponding microcell antenna unit.Type: GrantFiled: December 22, 2000Date of Patent: November 4, 2008Assignee: ADC Telecommunications, Inc.Inventors: Larry G. Fischer, David S. Russell, Philip M. Wala, Charles R. Ratliff, Jeffrey O. Brennan
