Description: A noncoherent, bandwidth-efficient modulation
scheme is proposed for frequency-hopping multiple-access
(FH-MA) networks. The proposed scheme is a combination
of noncoherent -ary amplitude-shift keying (NMASK) and
orthogonal frequency-division multiplexing (OFDM). Using
this scheme will minimize the required data bandwidth. The
number of frequency slots available to the users will increase
significantly for a fixed spread-spectrum bandwidth (BW55).
The effect of the multiple-access interference will be reduced.
Simple and accurate bit error rate expressions have been derived
for FH-OFDM-MASK in additive white Gaussian noise channels
and for FH-OFDM-ASK in Rayleigh fading channels.
Index Terms—Amplitude-shift keying (ASK), frequency hopping
(FH), -ary amplitude-shift keying (MASK), noncoherent,
orthogonal frequency-division multiplexing (OFDM), Rayleigh
channels. Platform: |

Description: 在现代无线通信技术中，扩频通信是一种具有较强抗干扰性能的技术，正交频分复用(OFDM)是一种具有较高数据传输速率和频谱利用率，并能有效对抗频率选择性衰落的多载波调制技术，因而将这二者结合起来构建系统势必会进一步提高系统的抗干扰和抗衰落性能，研究其结合技术也逐渐成为无线通信领域的热点。随着3G的兴起，即将推出的LTE也将采用OFDM技术（正交频分多路复用）。
由于OFDM的多载波特性，使得直接序列扩频技术和跳频技术能够与OFDM技术进行有效的结合。在本文中,我们研究了OFDM）以及相关抗干扰抗衰落技术。同时用matlab进行了仿真，仿真结果表明，本文提出的ICI干扰消除技术在ofdm中起到了很好的效果。
-In modern wireless communication technologies, spread spectrum communication is a kind of strong anti-jamming technology, the performance of orthogonal frequency division multiplexing (OFDM) is a kind of high data rate and spectrum efficiency, and can be effective against frequency selective fading of multi-carrier modulation technology, and combine the two build system is bound to further improve the system s anti-interference and decay resistance, and study the combining technology also gradually become a hot spot in the field of wireless communications. With the development of 3 g, the upcoming LTE will also use OFDM (orthogonal frequency division multiplexing) technology.
Because OFDM multi-carrier characteristic, the direct sequence spread spectrum and frequency hopping technology can be combined with OFDM technology effectively. In this article, we studied the OFDM technology) and related anti-interference resistance to decline. Matlab simulation was carried out at the same tim Platform: |
