Both architectures, designed under full-hardware paradigm, were described using Verilog HDL, targeted in Xilinx Virtex-5 and they were compared with existent approaches. The synthesis results showed a FPGA slice consumption of 1% for the transmitter and 3% for the estimator with 160 and 115\u2009MHz operating frequencies, respectively. The signal-to-quantization-noise ratio (SQNR) performance of the transmitter is about 82\u2009dB to support 4\/16\/64-QAM modulation. A Monte Carlo simulation demonstrates that the mean square error (MSE) of the channel estimator implemented in hardware is practically the same as the one obtained with the floating-point golden model. The high performance and reduced hardware of the proposed architectures lead to the conclusion that the DDST concept can be applied in current communications standards.<\/jats:p>","DOI":"10.1155\/2012\/236372","type":"journal-article","created":{"date-parts":[[2012,12,27]],"date-time":"2012-12-27T21:00:39Z","timestamp":1356642039000},"page":"1-13","source":"Crossref","is-referenced-by-count":0,"title":["Configurable Transmitter and Systolic Channel Estimator Architectures for Data-Dependent Superimposed Training Communications Systems"],"prefix":"10.1155","volume":"2012","author":[{"given":"E.","family":"Romero-Aguirre","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, CINVESTAV-GDL, 45019 Zapopan, JAL, Mexico"}]},{"given":"R.","family":"Parra-Michel","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, CINVESTAV-GDL, 45019 Zapopan, JAL, Mexico"}]},{"given":"Roberto","family":"Carrasco-Alvarez","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, UDG-CUCEI, 44430 Guadalajara, JAL, Mexico"}]},{"given":"A.
