Abstract
A controller (152) in a frequency hopped spread spectrum system (100) operating to assign a best available frequency hopping sequence among a plurality of sequences to at least one of a plurality of subscriber units (156) having predefined transmission intervals (12) and predefined transition intervals (14) comprises a power detector (50) that estimates a combination of a noise level and an interference level by measuring signal strength during a series of transition intervals for at least one sequence of channels among the plurality of sequences and a processor that computes an average noise and interference level for the at least one sequence of channels and ranks the at least one sequence of channels in accordance with the average noise and interference level computed.
