The invention relates to a client device (100) and a network access node (300) for transmitting and receiving a random access preamble. The modulation sequence for the random access preamble is based on a first sequence and a second sequence. The first sequence is a sequence from a set of...
Systems, methods, and other embodiments associated with preamble detection based on repeated preamble codes are described. According to one embodiment, an apparatus is provided that wirelessly receives a signal and calculates a differential output corresponding to a multiplication of the signal and a del...
3. Then,an integer frequency offset estimation algorithm using the differentiated sequence of the preamble is proposed,which is robust to the remaining timing offset. 本文提出一个有效的利用周期性前导字的OFDM定时同步与频偏估计算法。更多例句>> 2) preamble-less 无前导字 1. A full digital ...
In order to verify the performance of the scheme, the MATLAB is used to build a test system. The simulation results show that the proposed preamble satisfies the requirements of LTE-S system, and the better performance than previous researches is obtained....
13.There is no preamble and the register of the conversation is quite extraordinarily frank. 14.The preamble introduces research condition about an epic and the epic. 序言主要涉及了有关史诗的研究动态. 15.For me, the activities on Saturday were just a preamble. 对我来说, 星期六的活动只是一个...
Short preambles are based on a sequence length L=139 The sub-carrier spacing for short preambles is aligned with the normal NR sub-carrier spacing i.e. 15Khz, 30Khz, 60Khz and 120Khz. Short preambles use a sub-carrier spacing of: ...

The proposed method is based on the average magnitude difference function (AMDF). We present performance results for the proposed method for AWGN and Raleigh-fading channels in the context of IEEE 802.11a short preamble sequence. We also propose a preamble sequence based on Golomb sequence and ...
The proposed scheme is based on PRACH (Physical Random Access Channel) preambles and can significantly reduce the complexity of preamble detection at the eNodeB side.关键词: Long Term Evolution frequency estimation mobile handsets wireless channels LTE network PRACH preambles eNodeB side frequency ...
In the case of short preambles, the RACH resource described in Section 17.1.1 is based on the same numerology as the preamble. A short preamble thus always occupies 12 resource blocks in the frequency domain regardless of the preamble numerology. Table 17.2 lists the preamble formats available ...
