In signal processing, this definition can be used to evaluate the Z-transform of the unit impulse response of a discrete-time causal system.
An analyzer having an impulse response receives the impulse response of the system.
An intermediate channel impulse response estimator identifies paths within the initial channel impulse response and generates an improved intermediate channel impulse response.
The infinite impulse response filters (3.9, 3.10, 3.11, 3.12) simulate the response of finite impulse response filters.
An impulse response is estimated for a channel by estimating an intermediate impulse response of the channel.
An impulse response is measured for the selected antenna branch (full IRM) with a searcher.
The output for a unit impulse input is called the impulse response.
The response of a system to an impulse input is called the impulse response.
An impulse response block (108) forms for the received signal an impulse response which corresponds to each modulation method used.
An infinite impulse response filter section (18) is connected to the first finite impulse response filter section and has a second transfer function.
A cost function establishes a mean-square error associated with the estimated channel impulse response as compared to a desired impulse response signal.
FIR and IIR filters are used independently or in combination.
The invention relates to a direct-type FIR filter, a method for calculating a scalar product in a FIR filter, and a method for designing a direct-type FIR filter.
FIR or IIR filters of different bandwidth are provided.
The finger allocations can be done immediately after the corresponding IRM has been measured or alternatively together after the reduced IRM.
Then, a threshold function is applied to the estimated intermediate impulse response across at least a portion of the channel in order to provide an estimated final impulse response of the channel.
The impulse response measurement for the other antenna branch is performed only on the selected delay values (reduced IRM) with the searcher.
The value of the cost function varies based upon an offset value between the estimated channel impulse response and an equalized channel impulse response.
Any sound may be processed by using the impulse response so generated (111).
An expression for the impulse response of the system is given.
Consequently we call it the impulse response of the system.
Additionally, a system is described that estimates the impulse response (301) estimated for all multi-path signal components without reference to the actual angle of arrival of the signal.
A digital finite impulse response bandpass filter is described.
A method and system for an FIR filter are provided.
This is called the impulse response of the system.
The impulse response of the inverse filter is designed to be the inverse of the impulse response of the modulator stage.
