Access to a wireless communication system (100) by a subscriber station
(101-103) is facilitated by selecting (705) an access sequence from a set
of sequences that have been identified to have a low average of
peak-to-average-power-ratios of access signals generated by the set of
sequences and also based on a good cross-correlation of the access
signals; forming (714) the access waveform by generating an access signal
using the access sequence and appending in the time domain a cyclic
prefix to the access signal; and transmitting (715) the access waveform.
In some implementations, the access waveform is cyclically shifted (820)
before the cyclic prefix is appended, and in some implementations, the
signal is transmitted (710, 810) in a randomly selected sub-band of an
access interval.
