Title: Method and apparatus to compute a noise power estimate in a wcdma network
Inventor: URI M LANDAU
IPC: H04W52/56
Filed: 2007-08-03
Abstract: A method and an apparatus for computing a noise power estimate in a WCDMA(Wideband Code Division Multiple Access) network are provided to improve limitations and disadvantages of existing techniques by computing a noise power estimate for a downlink channel on the basis of an orthogonal sequence created for a transmitted signal. An addition block sums up a portion of DPCH(Dedicated Physical Channel) pilot bits in order to create an I(In-phase) component and a Q(Quadrature) component(302). The created I and Q components are multiplied by one or more orthogonal sequences so that one or more noise I components and one or more noise Q components can be created(304). In order to create at least one summed noise I component and at least one summed noise Q component, the addition block sums up at least one noise I component and at least one noise Q component respectively(306). Square blocks square at least one summed noise I component and at least one summed noise Q component respectively and create at least one squared noise I component and at least one squared noise Q component(308). The addition block sums up at least one squared noise I component and at least one squared noise Q component and creates a resulting summed noise component(310). A division block normalizes the resulting summed noise component so as to determine a noise power estimate for the downlink channel(312).
