With the introduction of a dither sequence and scaling factors, dithered Tomlinson-Harashima precoding (THP) has shown to outperform conventional spatial THP in multi-user MIMO systems. Through a careful analysis of dithered THP, this paper exhibits that it is not only possible, but also beneficial, to eliminate the dither sequence and develop efficient scale-only THP, and the key is to resolve the...
Standards development organizations around the world are making rapid advances in adopting MIMO-OFDM as the technology of choice for emerging broadband wireless standards. These include IEEE 802.11n - the next generation standard for wireless local networking, IEEE 802.16e - a new standard for metropolitan area networks, and 3 GPP Long Term Evolution (LTE) - the next generation standard for cellular...
In this paper, we propose a simple reduced-complexity decoding technique called bypass decoding for low-density parity-check (LDPC)-coded multiple-input-multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems. Employing the bypass decoding technique, the receiver of an LDPC-coded MIMO-OFDM system decodes a codeword in two steps based on the log-likelihood ratios (LLRs) of...
In this paper, we employ iteratively decodable codes in a turbolike receiver of a multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) communication system. With such a receiver, we compare the decoding complexity and performance of a turbo code with a low- density-parity-check (LDPC) code. For the same level of decoding complexity, we show that LDPC codes perform...
