Frequency Hopped-Orthogonal Frequency Division Multiple Access (FH-OFDMA) System Performance with Extending Quadratic Congruence (EQC) Hoping Code patternsDr Emad S AhmedFatima Al Azzawi
A frequency-hopping (FH) space-frequency (SF)-coded clustered orthogonal frequency division multiple access (OFDMA) system is considered. It is shown that SF coding reduces the number of collisions in OFDMA with FH provided that the subcarrier clusters are formed randomly at each hopping instant....
本发明涉及一种基于OFDMA的自组网多用户扩展方法,属移动终端通信技术领域.通过包括七个步骤,实现多址传输,极大提高传输效率,有效缩短传输时延,且具有抑制窄带干扰,抵抗多径效应和应对频率选择性衰落优点;将整个带宽分成若干个子频带间相互重叠的子信道,每个子信道包括若干正交调制的子载波,每个子信道分配给一个用户,也可...
A base station identification method for a frequency hopping-orthogonal frequency division multiple access (FH-OFDMA) based multi-input multi-output (MIMO) communication system that allocates a preamble, a pilot arrangement pattern and a pilot signal pattern per frame to each of base stations. A ...
In this paper, we present a novel multiple access scheme, referred to as CDM-FH-OFDMA, which is the extension of FH-OFDMA with code division multiplexing (CDM). This scheme can exploit the frequency diversity gain without the aid of channel coding. And it also can be employed in the ...
