Patent CA-2306327-C (CA)

IPC: H04B10/12
Filed: 2000-04-19
Granted: 2008-09-09
Abstract: A technique for controlling a wireless communication network to provide for blossoming capacity to a relatively high capacity state and/or wilting capacity to a relatively lower capacity state.  Connections in progress with active subscriber units are properly handled without the need to send explicit handoff commands from the base stations. The cell sites may be advantageously implemented with cable microcell integrators that comprise remotely deployed transceiving equipment that are interconnected to centrally located base transceiver station equipment via a broadband cable distribution network. In an initial relatively low capacity state, adjacent cells are operated at the same carrier frequency such that they form simulcast groups so that subscriber units traveling in adjacent cells will operate with the same radio channel. As demand increases, the power level of an auxiliary radio transceiver is gradually increased while the power level of the original transceiver in the cell is gradually decreased. Once the auxiliary transceiver is operating at full power on the second channel, the mobile units in the cell will have completed their internal soft handoff processing and switch over to the new channel. An analogous inverse process can be used to wilt the capacity of the system.

Title: Rfi canceller using narrowband and wideband noise estimators
Inventor: YEAP TET HIN
IPC: H04L25/02
Filed: 2000-06-09
Granted: 2011-12-06
Abstract: In order to overcome problems when using an adaptive filter for cancellation of common-mode noise in digital subscriber loops, caused by a portion of the differential signal being converted to common mode, which degrades the performance of the filter, a noise cancellation technique is proposed which compensates for this cross- coupled signal energy. In particular, a narrowband noise estimator is used to detect one or more noisy frequency bands of the common mode signal and derive therefrom a first noise estimation signal. A wideband noise estimation unit derives from the remainder of the common mode signal a second noise estimation signal. Both the first and second noise estimation signals are subtracted from the differential signal. The wideband noise estimation unit comprises a bandstop filter for removing the frequencies detected by the narrowband noise estimator, an analog-to-digital converter for converting the bandstopped signal to digital form, and an adaptive filter for deriving the second noise estimation signal from the digitized bandstopped signal and in the process compensating for phase and gain differences, especially attributable to the interference being injected at different points along the length of the channel.
