Sentence examples for parallel frequency from inspiring English sources

Orthogonal frequency division multiplexing (OFDM) is a multicarrier multiplexing technique, where data is transmitted through several parallel frequency subchannels at a lower rate.

The previous results considering a single carrier can be easily generalized for an OFDM-based system, assuming N c parallel frequency flat fading channels.

The optimized structure is parsed by the job creator of the Freq-0 K WF and Freq-400 K WF atomic workflow to create two parallel frequency files (Fig. 13).

Different correlation implementations include serial search acquisition (SSA) [6], which belongs to the traditional serial search scheme [7], parallel frequency space search acquisition (PFSSA) [8], and parallel code-phase search acquisition (PCPSA) [9].

Three-stage lowpass ΣΔ modulators have traditionally been used only for applications demanding very high resolution [33], but like shown in this article, the QΣΔM variant allows noncontiguous placement of the NTF zeros, and thus the quantization precision can be divided on multiple parallel frequency bands.

This kind of multi-band design for QΣΔM offers frequency agile flexibility and reconfigurability based on spectrum-sensing information [20] together with capability of receiving multiple parallel frequency bands [19], which are considered essential when realizing A/D interface for CR solutions [1].

To overcome the ISI in frequency-selective channels, we apply the OFDM scheme to the relay system, which converts the frequency-selective fading channel into a number of parallel frequency-flat channels free of ISI.

A low peak-to-average power ratio (PAPR) transceiver using a new parallel frequency-shift orthogonal keying (FSOK) technique is proposed for the multiuser uplink multi-carrier CDMA (MC-CDMA) system over multipath fading channels.

As OFDM can turn frequency-selective fading channel into several parallel frequency-flat ones, cooperative communication in time-dispersive channels is applicable by extending some DSTC methods, for example, the work in [20], to corresponding subcarriers at each relay in a form of OFDM symbol blockwise transmission.

Based on the above discussion, to simultaneously achieve multiuser detection and low-PAPR, as well as obtain frequency diversity gain to the greatest possible extent, we propose a novel parallel frequency-shift orthogonal keying (FSOK) technique for multi-carrier CDMA (MC-CDMA) systems.

Paralleling, frequency of genomes is relatively high in the SSRs relative density range of 12 ~ 44 bp/kb with the genome number of 226 (88.3% of all analyzed viruses), and 147 genomes (57.4%) have the SSRs relative density among 16 ~ 32 bp/kb; moreover, 85 genomes (33.2%) have the SSRs density of 20 ~ 28 bp/kb.
