A construction of 802.16e-compatible uplink sounding sequences is proposed. Ideally, the sounding signals should have low Peak-to-Average Power Ratio (PAPR) and low cross correlation. Existing 802.16e sounding sequences are variations of the punctured subsequences of a BPSK Golay sequence with PAPR that may exceed 7dB. The proposed sequences are variations of QPSK Golay sequences that maintain 3dB...
