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.

摘要： A noise thresholder of a baseband modem integrated circuit (BMIC) compares measured noise variances on corresponding receiver paths to a pre-established threshold minimum value. The noise thresholder assigns as a noise variance value for a corresponding receiver path either (a) a measured noise variance value for each receiver path having a measured noise variance that is larger than the pre-established threshold minimum, and (b) the pre-established threshold minimum value for each receiver path having a measured noise variance that is less than or equal to the pre-established threshold minimum value. A noise balancer performs noise balancing to provide a same signal to noise ratio (SNR) across all receiver paths, based on the assigned noise variances provided at the noise thresholder. A detection engine utilizes a lowest assigned noise variance value and outputs yielded by the noise balancer to simplify equalization computations while providing a high performance symbol detection capability.

摘要： A receiver with DFT based channel estimation having good noise suppression for both high and low signal-to-noise ratios providing advantages over conventional DFT estimators and Minimum-Mean-Square-Error (MMSE) estimators. The use of MMSE may be incorporated for estimation at the band edges providing further improvements. The received signal in the time domain, is transformed to the frequency-domain received signal via an N-point FFT (501). The frequency-domain received signal at the pilot locations is then used to obtain a “noisy” channel estimates at the pilot subcarriers by dividing the known pilot symbols in (503). Uniformly spaced pilots are assumed over a window of usable subcarriers. Padding is applied to the initial channel estimates at both sides of the band to account for unused subcarriers such as guard spacing. Weighting factors during power estimation may take into account various noise characteristics such as combinations of known and time-limited noise power characteristics.
