Orthogonal Frequency Division Multiplexing Modulation and Inter-carrier Interference Cancellation

Fuzzy Based Inter Cell Interference Cancellation in LTE System

LTE System is emerging wireless technology which offers reallocation and reutilization of the unused subcarriers. Not all the network runs with highest load at all the time. Therefore part of subcarrier always remains unused. In a multi radio environment LTE System allows the user to request for subcarrier while roaming from another service provider. In case the service provider has free subcar...

Inter Carrier Interference Cancellation in OFDM System

Orthogonal Frequency Division Multiplexing (OFDM) is a well known technique for the broadband wireless communication system. However, a main problem in OFDM is its vulnerability to frequency offset errors due to which the orthogonality is destroyed that result in Inter carrier Interference (ICI). ICI causes power leakage among subcarriers thus degrading the system performance. This paper studie...

Interference cancellation for non-orthogonal multiple access used in future wireless mobile networks

Non-orthogonal multiple access (NOMA) is suggested as a radio access candidate for future wireless mobile networks. It utilizes the power domain for user multiplexing on the transmitter side and adopts a successive interference cancellation (SIC) as the baseline receiver scheme, considering the expected mobile device evolution in the near future. However, recent research focuses more on the per...

Iterative Frequency-domain Interference Cancellation of Inter-code Interference and Inter-antenna Interference

あらまし 限られた帯域幅で高速パケット伝送を実現するには,マルチ送受信アンテナ(MIMO)多重とハイブリッド自 動再送要求(HARQ)の併用が有効である.筆者らは最近,マルチコード DS-CDMA MIMO 多重伝送を対象として,繰り返 し周波数領域干渉キャンセル(FDIC)を提案した.2 次元最小平均 2 乗誤差規範に基づく周波数領域等化(2D MMSE-FDE) でコード間干渉(ICI)と他アンテナ干渉(IAI)を低減した上で,FDIC によって残留 IAI を抑圧する.この繰り返し処理によ って信号分離精度を向上させている.しかし,FDIC では残留 IAI のみを抑圧する構成となっており,残留 ICI について はそのままである.そのため,残留 ICI が信号分離精度向上に制限を与えてしまう.そこで本論文では,残留 ICI 及び残 留 IAI を同時に低減する繰り返し FDI...
