WHTDM: Walsh-Hadamard Transform Division Multiplexing for Doubly-Selective Channels
Wang Hao, Yuan Zhonghao, Chi Yonggang +3
We propose Walsh-Hadamard Transform Division Multiplexing (WHTDM), a multicarrier waveform that replaces the conventional IFFT/FFT pair in OFDM with a real-valued, unitary Walsh-Ha…
