In the one-bit massive multiple-input multiple-output (MIMO) channel scenario, the accurate channel estimation becomes more difficult because the signals received by the low-resolution analog-to-digital converters (ADC) are quantized and affected by ch…

In this paper, multi-unmanned aerial vehicle (multi-UAV) and multi-user system are studied, where UAVs are served as aerial base stations (BS) for ground users in the same frequency band without knowing the locations and channel parameters for the user…

In this paper, a novel anti-interference direction finding (DF) method for amplitude comparison method based on cyclostationarity is proposed. With the periodic properties of the communication signals, the desired signal’s amplitude value can be effect…

Mobile-edge computing (MEC), enabling to offload computing tasks on mobile devices towards edge servers, can reduce the terminals cost. However, a single MEC sever usually has limited computing capabilities, which can not meet a large number of termina…

In this paper, we propose a preamble-based medium access control (P-MAC) mechanism in Ad-Hoc network. Different from traditional carrier sense multiple access (CSMA) in Ad-Hoc network, P-MAC uses a much shorter preamble to establish the network. First,…

We study a downlink non-orthogonal multiple access (NOMA) system, in which a base station (BS) serves a near user and a far user on the same frequency band simultaneously. Due to physical obstacles or heavy shadowing, there is no direct link from the B…

Orthogonal frequency division multiplexing (OFDM) waveform is promising to converge communications and sensing functionalities for future wireless applications. This paper presents a novel method to improve the OFDM-based sensing accuracy by estimating…

To better support the emerging vehicular applications and multimedia services, vehicular edge computing (VEC) provides computing and caching services in proximity to vehicles, by reducing network transmission latency and alleviating network congestion….
