Differential space-time modulation over frequency-selective channels

  title={Differential space-time modulation over frequency-selective channels},
  author={Hongbin Li},
  journal={IEEE Transactions on Signal Processing},
We present herein a new differential space-time-frequency (DSTF) modulation scheme for systems that are equipped with an arbitrary number of transmit antennas and operate in frequency-selective channels. The proposed DSTF modulator consists of a concatenating spectral encoder and differential encoder that offer full spatio-spectral diversity and significant coding gain. A unitary structure is imposed on the differential encoder to admit linear, decoupled maximum likelihood (ML) detection in… CONTINUE READING
