摘要：
Methods and apparatus to perform fractional-spaced channel estimation for frequency-domain equalizers in high-speed downlink packet access (HSDPA) receivers are disclosed. An example method comprises computing a first fractionally-spaced time-domain channel estimate from an oversampled CDMA signal, and computing a first chip-interval frequency-domain equalizer (FDE) coefficient from the first fractionally-spaced channel estimate.
