摘要： A method and system generates channel response estimates by performing time direction filtering of first channel estimates obtained from frequency direction filtering. A baseband integrated circuit (BBIC) receives information signals comprising reference signals, control signals provided by physical control channels, and data signals provided by physical data channels. Using a latency requirement of a physical channel, symbol selection logic selects valid reference signal symbol positions corresponding to first channel estimates from among frequency filtered received reference signals. A coefficient set selection logic selects a set of filter coefficients from among multiple sets of pre-optimized coefficients, utilizing at least one of (a) the latency requirement, (b) a channel condition, and (c) the selected reference signal symbol positions. A time direction filter uses the selected filter coefficients to filter the first channel estimates in order to generate a channel response estimate for a resource element of the physical channel.
