![]() ![]() ![]() The integrated sensing and communication (ISAC) paradigm is being proposed for 6G as a new feature of the physical layer (PHY), for tackling dual-functional applications, i.e., demanding radio-sensing and communication functions, such as the Internet of Things (IoT) and autonomous driving systems. The proposed polyphase code named P43code is produced by combining left and right shifted versions of P4\documentclass code compared to existing alternatives. In this paper, a new polyphase code is proposed that exhibits good auto-correlation and cross-correlation properties to reduce peak side-lobe level (PSL) and integrated side-lobe level (ISL). In general, the side-lobes behaviour performance of received signals is observed by their correlation with other contemporary signals. Targets generating weak signals tend to hide in undesired side-lobes creating ambiguity. Range side-lobes suppression which is responsible for detection ambiguity is a challenging task in pulse compression (PC) radar. An appropriate system parameterization in the 77GHz industrial, scientific and medical (ISM) band, allows to achieve a range resolution of 30.52 cm and a velocity resolution of 0.67 m/s and to reduce the periodogram computation time up to around 98.84%. Furthermore, since the dimensions of the data matrix can be much larger than the number of targets to be detected, we propose a sparse Fourier transform based Fourier projection-slice (FPS-SFT) algorithm to reduce the computational complexity of the 2D-Periodogram. Moreover, we improve the estimation performance in low signal to noise ratio (SNR) conditions using the discrete Fourier transform channel estimation (DFT-CE) and we show that Zadoff-Chu precoding (ZCP) adopted for communication, does not degrade the radar estimation in good SNR conditions. We estimate the targets parameters (range and velocity) using a 2D-Periodogram. The latter knows the transmitted signal and listens to echoes coming from the reflection of fixed or moving targets. We assume that the transmitting antenna Tx is colocated with a monostatic radar. We propose in this work a radar detection system for orthogonal-frequency division multiplexing (OFDM) transmission. The proposed scheme is beneficial for B5G communication systems that allow localization and sensing as key features of next-generation wireless networks. ![]() The proposed radar-aided communication scheduling scheme provides a more flexible design by adding new parameters, resulting in a more efficient algorithm in a broad variety of scenarios. The proposed algorithm schedules the available resources by extracting information from the radar echo. Unlike the conventional scheduling mechanisms where signal-to-interference-plus-noise ratio (SINR) is exploited, this paper proposes a new radar-aided communication scheduling algorithm by utilizing parameters such as range and velocity with the classical SINR measurements. We investigate an echo-based scenario in the radar-aided vehicular communication system in which an echo is reflected from a target. More efficient scheduling algorithms are needed with the wide range of applications that the wireless environment is experiencing. All of our antennas indicate whether they are a uni-directional or multi-directional antenna.Radar and communication coexistence is an upcoming technology with numerous research opportunities in the medium access control (MAC) layer, particularly in scheduling and radio resource management (RRM). If the transmitters are positioned more than 20° apart, it is best to use a multi-directional antenna. Check the Black markers on the map, and if all of your desired stations are transmitting from the same area or within 20° of each other, you can use a uni-directional antenna: Check out the Element Uni-directional long range antenna. Louis, the transmitters are scattered around the city. In some cities like New York, Chicago and Los Angeles, all stations are broadcast from one central area the Empire State and GE Buildings in New York, the Sears Tower or Hancock Building in downtown Chicago, and Mt. You might need a uni-directional or multi-directional antenna.The antenna you choose should be based on the tower located farthest from your location. Use the Heading listed in the results below and a compass to aim your antenna towards the towers. Determine how far your antenna will be from the transmitters.For UHF (Channels 14 - 51), you will receive crystal clear reception with any of our other antennas. Check out our ClearStream 1MAX, ClearStream 2MAX or ClearStream 4MAX HDTV antennas based on their range. If the Affiliate channels are for high-frequency VHF stations (Channels 7 – 13), you will need a VHF antenna. Look at the column heading in dark blue for UHF or VHF. Check to see if the digital channels in your area broadcast on the UHF or VHF band. ![]()
