Equalization Techniques For Multipath Mitigation in Aeronautical Telemetry
… decision-feedback minimum mean squared error (DF-MMSE) concept to the two compatible offset QPSK waveforms (FQPSK and SOQPSK-TG) that constitute the ARTM Tier-1 waveforms. An adaptive version of the DF-MMSE equalizer is developed and applied to this application. In the presence of frequency …

Characterization and Evaluation of Non-Line-of-Sight Paths for Fixed Broadband Wireless Communications
… (Z-F) and Minimum Mean Square Error (MMSE) equalizers employed on these channels had a significant impact on the link quality. In many cases, the performance of the MMSE equalizer performed only slightly better than the Z-F equalizer. However, when deep nulls were present in the …

Sparse nonlinear optimization for signal processing and communications
… estimation based minimum mean-square-error (MMSE) turbo equalizer is proposed for large MIMO detection. The MIMO channel estimation is performed jointly with the MMSE equalizer and the maximum a posteriori probability (MAP) decoder. The proposed MIMO detection scheme has been tested by …

Transmission and detection for space-time block coding and v-blast systems
… a fast sub-optimal detection scheme using MMSE equalizer is also proposed, especially for channels with large delays. The Chapter 5 focuses on the V-BLAST system, an important high-rate space-time data transmission scheme. A reduced complexity ML detection scheme for VBLAST systems, which …

Turbo equalization using message passing methods with higher order modulation signaling
… equalization algorithm which consists of MAP equalizer and MAP decoder. However, this algorithm gives rise to an impractical computational complexity. The computational burden leads us to consider the turbo equalization based on minimum mean squared error (MMSE) linear equalizer which reduces …
