Patent CA-2358382-A1 (CA)
Title: Channel identification in communications networks
Inventor: WAN PING WAI
IPC: H04B10/07
Filed: 2001-10-05
Abstract: Channels in an optical WDM network are each identified by at least two dither tones with which the channel is modulated, the dither tones alternating with a predetermined periodicity so that at any instant each channel is modulated by only one dither tone.    The dither tones are continuously generated at precise frequencies. Channel detection by detecting the dither tones, for channels having optical powers over a wide dynamic range, makes use of an FFT process which can detect dither tones for high power channels in a single operation. Coherent averaging of FFT results over time is used to detect dither tones for low power channels over multiple FFT operations.

Inventor: VADEKAR ASHOK
IPC: G06F7/72
Filed: 2002-01-29
Abstract: The applicants have recognized an alternate method of performing modular reduction that admits precomputation. The precomputation is enabled by approximating the inverse of the truncator T, which does not depend on the scalar. The applicants have also recognized that the representation of a scalar in a ~- adic representation may be optimized for each scalar that is needed. The applicants have further recognized that a standard rounding algorithm may be used to perform reduction modulo the truncator. In general terms, there is provided a method of reducing a scalar modulo a truncator, by pre-computing an inverse of the truncator. Each scalar multiplication then utilizes the pre- computed inverse to enable computation of the scalar multiplication without requiring a division by the truncator for each scalar multiplication.
