“…Massive MIMO can achieve good SIR performance even under the application of simplified weighting such as EGC [20] or maximal ratio combining (MRC) [21]. Consider MAS-WE application scenario where EBS and RSs are deployed at fixed and high location, above feature can be more feasibly guaranteed than the fading channel environment.…”

This paper newly proposes a frequency domain backoff scheme dedicated to continuous beamforming space division multiple access (CB-SDMA) on massive antenna systems for wireless entrance (MAS-WE). The entrance base station (EBS) has individual base band signal processing units for respective relay stations (RSs) to be accommodated. EBS then continuously applies beamforming weight to transmission/reception signals. CB-SDMA yields virtual point-to-point backhaul link where radio resource control messages and complicated multiuser scheduling are not required. This simplified structure allows RSs to work in a distributed manner. However, one issue remains to be resolved; overloaded multiple access resulting in collision due to its random access nature. The frequency domain backoff mechanism is introduced instead of the time domain one. It can flexibly avoid co-channel interference caused by excessive spatial multiplexing. Computer simulation verifies its superiority in terms of system throughput and packet delay.

“…Furthermore, most of the mobile reception system, 4 antennas are mounted on a vehicle (Front: 2 antennas, Rear: 2 antennas) and array signal processing techniques is adopted to improve the reception quality. The authors proposed a combining system and proved that our combing method has better performances than the conventional system [1,2]. To improve the performance further, the authors proposed a new combing method (Incoming waves separating system by adaptive array antenna) [3].…”

In terrestrial digital TV broadcasting in Japan, OFDM is utilized as a modulation scheme. However, the communication quality could be seriously deteriorated at the high speed mobile reception (Ex. vehicle). Furthermore, most of the mobile reception system, 4 antennas are mounted on a vehicle (Front: 2 antennas, Rear: 2 antennas).The authors proposed a new combing method (Incoming waves separating system by adaptive array antenna). In this paper, the performances in case of 4 directional antennas are evaluated. Furthermore the performance in more complicated environment is evaluated. From experimental results, it is clarified that the BER performances of the proposed system are superior to the conventional system.

In our application targeted here, four on-glass antenna elements are set in an automobile to improve the reception quality of mobile ISDB-T receiver. With regard to the directional characteristics of each antenna, we propose and implement a joint Pre-FFT adaptive array antenna and Post-FFT space diversity combining (AAA-SDC) scheme for mobile ISDB-T receiver. By applying a joint hardware and software approach, a flexible platform is realized in which several system configuration schemes can be supported; the receiver can be reconfigured on the fly. Simulation results show that the AAA-SDC scheme drastically improves the performance of mobile ISDB-T receiver, especially in the region of large Doppler shift. The experimental results from a field test also confirm that the proposed AAA-SDC scheme successfully achieves an outstanding reception rate up to 100% while moving at the speed of 80km/h.
