Abstract
In this thesis, we find the Laurent Decomposition of constant envelope orthogonal frequency division modulation (CE-OFDM). The CE-OFDM signal is represented as a sum of finite numbers of amplitude modulated signal and decreases the difficulty to analysis CE-OFDM. We use the Laurent Decomposition of CE-OFDM to do two applications. First, we analyze the spectrum and derive the power spectral density (PSD). The difference of spectrum is compared by different modulation index. Second, a linear receiver is designed to CE-OFDM, and maximum likelihood (ML) detection is applied to demodulate the received signals. Under AWGN channel, we derive the union bound of bit error rate when this linear receiver is used to CE-OFDM. At last, we observe the effect to bit error rate by different modulation index.
