Orthogonal Constant-Amplitude Sequence Families for System Parameter Identification in Spectrally Compact OFDM

Shih-Hao Lu, Char-Dir Chung, Wei-Chang Chen +1

In rectangularly-pulsed orthogonal frequency division multiplexing (OFDM) systems, constant-amplitude (CA) sequences are desirable to construct preamble/pilot waveforms to facilita…
