Uncompressed High-Definition video streaming over extremely high frequency using wireless technologies, also known as WirelessHD, is a challenge problem because of the high data rate requirement and channel variations. The advantages in RF technology and the huge bandwidth available in the 57-66 GHZ millimeter wave open new era for High Definition applications and high data rates communication. Retransmission is not favored for HD multimedia transmission as any latency may cause flickering. So, powerful error correction and detection is needed to detect any corrupted pixels and recover it to guarantee the communication. In this study, we proposed a system that uses Low Density Parity Check (LDPC) code for error detection and correction and OFDM technique for protecting video signal from fading. A suggested frame partitioning technique is applied to perform spatial diversity.To judge on the proposed system, peak signal to noise ratio and symbol error rate will be used at the receiver for testing the received frame quality. Simulations using uncompressed videos indicate that the proposed system can give low bit error rate and high peak signal to noise ratio after transmitting the frame over AWGN and Rayleigh channels.

“…Although gigabit wireless backhauls have been around for a few years, most of them operate in the mm-wave bands of [71][72][73][74][75][76] GHz (commonly referred to as E-band) with a data rate up to 1.25 Gbps. Owing to the atmospheric absorption at E-band, however, these backhauls are limited to a distance of just a few kilometres (Singh et al 2008, Dyadyuk et al 2007). To reach longer distances, wireless backhauls must operate at microwave frequencies.…”

“…Additionally, the heavy rainfall also brings about 7 dB/km attenuation for the mmWave propagation at 28 GHz [1,2]. To overcome the high path and penetration losses, the multiple-input and multiple-out (MIMO) with antenna beamforming plays a pivotal role in establishing and maintaining a robust communication link [3][4][5][6][7][8]. Additionally, since the wavelength of mmWave communications is smaller than that of the sub-6 GHz wave, the large antenna arrays can be implemented in smaller size at both the transmitter and receiver.…”

Abstract:In millimeter wave (mmWave) communications, the feature of relatively large signal absorption and directional transmission render new challenges for wireless communications and signal processing. To further improve the performance of mmWave communications, a novel radar-aided mmWave communication (RAMC) approach is proposed, which can be used in vehicular communications. There are two parts in the proposed RAMC system, including the radar subsystem and the mmWave communication subsystem. In the radar subsystem, the bistatic co-prime multi-input and multi-output (MIMO) arrays are considered. With the radar antenna arrays, both the directions of departure (DoD) and the directions of arrival (DoA) are estimated. Additionally, the compressed sensing (CS)-based method is proposed to obtain the target positions. Using the estimated angle and position information, the channel estimation and feedback link of the mmWave communication subsystem can be eliminated. Moreover, a hybrid beamforming algorithm is proposed in the mmWave communication subsystem, which can overcome the shortage of the analog-only beamforming. Simulation results show that the better estimation performance can be achieved by the bistatic co-prime MIMO arrays than that by the traditional uniform linear arrays (ULA), and with the radar aided, the mmWave communication subsystem can reduce the beam search time, and the cell discovery time is improved significantly.
