摘要： Low-complexity channel noise reduction method and apparatus for multi-carrier mode in wireless LANs are disclosed. The method selects an optimal frequency domain channel impulse response by using a known long training sequence and a highly protected signaling sequence of the multi-carrier mode frame structure to ensure the receiver to have a good operation threshold in different time-delay spread environments at the cost of a low complexity. Instead of detecting time domain channel responses, the method directly performs noise reduction to a noise-containing frequency domain channel by using preset Wiener filtering coefficients to obtain multiple frequency domain channel responses, among which there must be a relatively optimal frequency domain channel response. The relatively optimal frequency domain channel response can be selected by using the highly protected signaling sequence to calculate the signaling frequency domain channel.

摘要： A method for determining coefficients of a family of cascaded second order Infinite Impulse Response (IIR) parametric filters used for equalizing a room response. The method includes determining parameters of each IIR parametric filter from poles or roots of a reasonably high-order Linear Predictive Coding (LPC) model. The LPC model is able to accurately model the low-frequency room response modes providing better equalization of loudspeaker and room acoustics, particularly at the low frequencies. Advantages of the method include fast and efficient computation of the LPC model using a Levinson-Durbin recursion to solve the normal equations that arise from the least squares formulation. Due to possible band interactions between the cascaded IIR parametric filters, the method further includes optimizing the Q value of each filter to better equalize the room response.
