Abstract:
1. A method for signal processing performed by a wireless receiver, the method comprising: receiving, combining and despreading Dedicated Physical Channel (DPCH) pilot symbols from a wireless signal; generating a post-rotation quadrature component signal based on the despread DPCH pilot symbols and on a pilot sequence transmitted by a transmitter; computing the power of said post-rotation quadrature signal to produce a noise power estimate; extracting the Dedicated Physical Channel (DPCH) pilot symbols from said received signal and generating an in-phase (I) component and a quadrature (Q) component; multiplying said generated I component by Q component of said transmitted pilot sequence to generate a first post rotation component; and multiplying said generated Q component by I component of said transmitted pilot sequence to generate a second post rotation component.
