WebAug 15, 2008 · Constant envelope OFDM (CE-OFDM) transforms the OFDM signal, by way of phase modulation, to a signal designed for efficient power amplification. At the receiver, the inverse transformation - phase demodulation - is applied prior to the conventional OFDM demodulator. This section principally introduces a new CE-OFDM multi-carrier RadCom fusion approach. The constant envelope RadCom fusion approach is based on the CE-OFDM system, in which the real-valued OFDM signals are modulated by a phase modulator to obtain constant amplitude signals. See more The ambiguity function is defined as [22] The three-dimension graph, which is obtained by χ(τ, fd ) 2, is called the ambiguity graph. Meanwhile, the ambiguity graph displays the … See more The process methods of range and relative velocity for CE-OFDM RadCom system are completely independent from the transmitted information. Furthermore, all processing … See more When input of detection receiver is AWGN with a given α, provided that MQAM and 2πhare fixed, the output matrix of array processor can be expressed as where c is proportion coefficient … See more Radar detection is a very complex process.

Novel Low-Complexity Receivers for Constant Envelope OFDM
WebIt is shown that CE-OFDM is naturally noncoherent since the effect of an unknown phase shift at the receiver is eliminated by the matched-filter bank following the front-end phase demodulator. A noncoherent constant envelope orthogonal frequency-division multiplexing (CE-OFDM) receiver is proposed. It is shown that CE-OFDM is naturally noncoherent … WebJul 10, 2024 · In this paper, we investigate Constant-Envelope Multicarrier (CE-MC) waveforms for future adoption in mm-Wave 5G transmissions, namely: Constant-Envelope Orthogonal Frequency Division Multiplexing (CE-OFDM) and Constant-Envelope Single-Carrier OFDM (CE-SC-OFDM). WebJun 7, 2024 · This paper introduces a constant envelope multi-carrier RadCom approach with the advantages of high data rate, high ability of anti-fading, simple radar processing, and constant 0 dB PAPR.
