Patent ID: 7406120

Claim:
A method of channel impulse response estimation, usable with a digital wireless communication channel, comprising the steps of: (a) providing a first pseudonoise (PN) sequence for a first packet; (b) with use of said first PN sequence, providing a first training sequence; (c) transmitting said first training sequence via said communication channel via a first packet including first data; (d) receiving said first packet and said first training sequence as transmitted via said communication channel; (e) forming a Toeplitz-type representation comprising an invertable Gramm matrix, by use of a replica of said first training sequence as provided in step (b) and use of said first training sequence as received in step (d); (f) processing said Toeplitz-type representation to determine coefficients representative of the channel impulse response of said communication channel; and (g) using said coefficients in processing of said first data as included in the first packet.
