Abstract
Existing GSG (Gold Sequence Generator) generates only 1 bit data per clock cycle. Thus it may cause delay to the data communications. In this paper, we propose the GSG with parallel outputs for high speed data communications. Through simple matrix multiplications, we could not only derive a recursive formula in parallel form but also implement the GSG with multiple outputs. Experimental results show that though the total area and clock period of the proposed scheme are 3-13% and 21-23% larger than those of the existing scheme, our GSGs with parallel outputs improve 2, 4 and 6 times the throughput, respectively, compared with the existing GSG with single output. We also applied our GSGs to a MMSE-SIC receiver for MIMO-OFDMA systems. Therefore, we remarkably improve the throughput of the MIMO detector with the parallel processing of the data communications. ©2008 IEEE.
