Channel response adaption procedure in mobile communications receiver - using recursive adaption algorithm to correct initial estimated channel response coeffts.

摘要

The adaption method, applied during a TDMA burst, samples the received burst which is divided into an odd number of sectors (A-N, A+N), the channel response within each sector taken as a constant with a test sequence at the centre of each burst allowing initial estimation of the channel response. Each sector is processed in a corresponding step to allow the channel response coefficients provided from the estimated channel response to be corrected using a recursive adaption algorithm employing a correlation matrix. USE/ADVANTAGE - Preventing fading in mobile communications. Copes with vehicle speeds above 250 km/h.
