We consider a cell-free wireless system operated in Time Division Duplex (TDD) mode with user-centric clusters of remote radio units (RUs). Since the uplink pilot dimensions per channel coherence slot is limited, co-pilot users might incur mutual pil

In IEEE 802.16 uplinks, the permutation of data on a frequency domain is performed when logical subchannels are transformed to physical subchannels to scatter deterioration of the radio propagation environment via inter-cell interference. However, it

In this paper, we propose a burst construction and packet mapping scheme in the orthogonal frequency-division multiple access (OFDMA) downlinks of IEEE 802.16 systems. In the standard of the systems, there are some restrictions on the usage of downli

In this paper, we propose a Quality of Service (QoS) packet scheduling algorithm for the IEEE 802.16 system and evaluate the algorithm on hardware. The proposed algorithm controls packets based on a deadline for each packet determined from QoS parame

This paper proposes a multihop mobile communications system using an MC-CDMA transmission technique in the forward links. In the system, it is assumed henceforth that each mobile station has a relaying function where a frequency band is used both in

This paper presents novel broadcast methods for an inter-vehicle communications system for ITS. During inter-vehicle communications, it is essential that emergency information be broadcast to surrounding vehicles. Emergency information such as emerge

It is expected that vehicles have on-board terminals to communicate with the fixed network and also with surrounding vehicles in the near future. This paper explains our developed inter-vehicle P2P (peer-to-peer) communication experimental on-board t

A timing detection scheme for multipath signals is proposed for wireless OFDM systems. The multipath signal timings are obtained in the process of suppressing the interference and obtaining the optimal weight vectors of an adaptive array antenna. The
