WebDelay alignment modulation: Enabling equalization-free single-carrier communication. H Lu, Y Zeng. IEEE Wireless Communications Letters 11 (9), 1785-1789, 2024. 7: 2024: Delay alignment modulation: Manipulating channel delay spread for efficient single-and multi-carrier communication. WebApr 13, 2024 · Thanks to the Walsh Hadamard transform (WHT), the modulation and demodulation do not require complex domain multiplications. For the proposed OTSM, we first derive the input-output relation in the delay-sequency domain and present a low complexity detection method taking advantage of zero-padding. We demonstrate via …
