Multiple-antenna systems have been shown to provide significant performance improvements over single-antenna systems. Theoretical analysis, simulation and experimental testing corroborate improvements in capacity and transmit power/energy savings. Unfortunately, co-located MIMO radios have numerous disadvantages compared to single-antenna radios; such as more complex RF and modem signal processing,...
Lattice reduction-aided equalization techniques have emerged as a low-complexity method to achieve the same diversity as maximum likelihood detectors. We address the VLSI implementation of these LR-aided equalizers by modifying the CLLL algorithm from a fixed-point hardware perspective. We then apply the modified algorithm together with additional micro-architecture and operation scheduling enhancements...
In this paper we apply a new joint synchronization-pilot sequence (JSPS) optimization design technique to multiple transmitter OFDM systems. One objective in the design of the JSPS for MISO transmissions is to eliminate the requirement for the different preamble fields used for coarse and fine synchronization and channel training. In this work, independent JSPSs are designed for each transmitter in...
