System and method for improving the performance of OFDM systems

A method for improving an OFDM system performance, comprising:

• performing channel estimation on a preamble in a received signal to obtain a first estimate;
• making a decision pertaining to selective use/choice of a smoothing filter to improve the first estimate, wherein one parameter on which said decision is based comprises an estimated SNR.

A method for improving the performance of an OFDM system, comprising:

• performing channel estimation on a preamble in a received signal to obtain a first estimate;
• deciding whether to perform decision feedback based correction to improve the channel estimate, wherein the decision whether to perform decision feedback based correction is based on a comparison of a data rate of the received signal with a threshold value in IEEE 802.11 a/g applications.

An article comprising:

• a storage medium having instructions that, when decoded by a computing platform, will result in a method for improving the performance of an OFDM (Orthogonal Frequency Division Multiplexing) system, comprising:
• performing channel estimation on a preamble in a received signal to obtain a first estimate;
• making a decision pertaining to selective use/choice of a smoothing filter to improve the first estimate, wherein one parameter on which said decision is based comprises an estimated SNR.
