Channel Estimation

BaseChannelEstimator(resource_grid[, ...])	Abstract block for implementing an OFDM channel estimator.
BasePilotChannelEstimator(resource_grid[, ...])	Abstract block for implementing an OFDM channel estimator that first estimates the channel at the pilot locations and then obtains channel estimates for the entire resource grid through interpolation.
LSChannelEstimator(resource_grid[, ...])	Least-squares (LS) channel estimation for OFDM MIMO systems.
LMMSEChannelEstimator(resource_grid, ...[, ...])	LMMSE channel estimation for MIMO OFDM systems, where LMMSE filtering (interpolation and smoothing) is applied across time, frequency, and (optionally) spatial dimensions.
BaseChannelInterpolator([time_avg, ...])	Abstract class for implementing an OFDM channel interpolator.
NearestNeighborInterpolator(pilot_pattern[, ...])	Nearest-neighbor channel estimate interpolation on a resource grid.
LinearInterpolator(pilot_pattern[, ...])	Linear channel estimate interpolation on a resource grid.
tdl_freq_cov_mat(model, subcarrier_spacing, ...)	Compute the frequency covariance matrix of a TDL channel model.
tdl_time_cov_mat(model, speed, ...[, ...])	Compute the time covariance matrix of a TDL channel model.
