Abstract

The baseband signal processing of the ALTAIR wireless in-building network (WIN) is described. The discussion covers the 19-GHz oscillator, burst processing, packet detection, symbol clock synchronization and gain and offset correction. The algorithms described are carried out in a single ASIC composed of 60000 active gates. The implemented procedures allow for parallel processing, which significantly reduces the computation time and therefore leads to preserving high bandwidth efficiency. The learning processes that acquire information about packet parameters and the adjustment operations in the receivers are executed in 3 mu s.<>
