“…It is assumed that the channel coding compensates residual distortions to achieve a coded bit error rate (BER) below 10 26 or a packet error rate below 10%. This assumption is supported by simulations [16].…”

The large bandwidth of the 60 GHz frequency band enables wireless short-range applications with data rates of several Gbit/s. The German project EASY-A has focused on early prototype implementations for selected applications, although no generally accepted 60 GHz standard has been available at the time. The implementations are based on application-oriented physical layer designs and link-budget investigations that account for the scenario-specific channel characteristics and for different integration technologies. This paper discusses the results of these investigations and details the hardware implementation of the digital baseband processing that relies on considerable parallelization. The link-budget results show that SiGe technology allows for 1 Gbit/s at a range of 3.5 m in non-line-of-sight environments, while up to 10 Gbit/s are feasible at more than 1 m in case of strong line of sight.

“…We choose the frequency-domain equalization (FDE), ideal synchronization and ideal channel estimation in this simulation chain. Differing from performance evaluation in [5], this paper considers the effect of hardware impairments, including phase noise and non-linear distortion of power amplifier (NLPA), incurred by ultra-high carrier frequency and ultra-wide bandwidth [9]. The CC(171,133), RS(255,239)-CC(171,133) and LDPC(672,336) are considered as channel coding schemes for the 60GHz SC-PHY WPAN System, referring to ECMA 387 standard, IEEE 802.15.3c standard and IEEE 802.11ad Standard [8].…”

“…The channel coding schemes constitute a critical aspect for 60GHz WPAN systems, and it is widely studied in [3], [4] and [5]. The frame-error rate performance evaluation of LDPC and convolutional codes (CC) in 60GHz OFDM-based wireless systems has been presented in [5], which shows LDPC obtains higher coding gain (about 1dB in line-of-sight (LOS) channel and over 2dB in non-line-of-sight (NLOS) channel compared to CC).…”

In this paper, we make a performance comparison between convolutional(171,133) codes (CC), concatenated RS(255,239)-convolutional(171,133) codes (RS-CC) and LDPC(672,336) based on 60GHz single carrier physical layer (SC-PHY). With the effect of phase noise and non-linear distortion of power amplifier (NLPA) taken into account, RS-CC reveals higher robustness against the effect over LDPC, and it has the better bit-error rate performance than LDPC. Over and above, a forward independent sliding-block architecture for Viterbi decoders (FISB-VD) is proposed to achieve multigigabit inner-CC decoding of the RS-CC. A 16-parallel FISB-VD has been implemented in a Xilinx Virtex-6 FPGA device, of which the maximum decoding rate can be up to 3.2 Gbps.

“…It is straightforward to use parallel Viterbi decoding in the receiver baseband. However, it has been shown in [4,5] that parallel Viterbi decoders in the receiver baseband result in massive hardware complexity and power consumption. The problem will become more severe if a higher decoding throughput is targeted (i.e., 10 Gbps) for a battery powered user terminal in the future [6].…”

Sequential decoding can achieve a very low computational complexity and short decoding delay when the signalto-noise ratio (SNR) is relatively high. In this article, a low-complexity high-throughput decoding architecture based on a sequential decoding algorithm is proposed for convolutional codes. Parallel Fano decoders are scheduled to the codewords in parallel input buffers according to buffer occupancy, so that the processing capabilities of the Fano decoders can be fully utilized, resulting in high decoding throughput. A discrete time Markov chain (DTMC) model is proposed to analyze the decoding architecture. The relationship between the input data rate, the clock speed of the decoder and the input buffer size can be easily established via the DTMC model. Different scheduling schemes and decoding modes are proposed and compared. The novel high-throughput decoding architecture is shown to incur 3-10% of the computational complexity of Viterbi decoding at a relatively high SNR.
