Much like massive MIMO is needed to operate current high- frequency networks, moving to even higher frequency bands in B5G systems will further the troubles of signal attenuation. While beamforming can aid in this, it cannot compensate for potential multi-path or no-line-of-sight problems in ...
1. Introduction In recent years, the amount of spatial data generated by Internet of Things (IoT) sensors, social networks, and moving vehicles has significantly increased, which has led to many research efforts to develop processing frameworks that can handle spatial big data, e.g., JD Urban...
The time complexity of Algorithm 1 includes:(1) Calculate all space-to-space offset values, namely, 𝒪(∣𝒮𝑝∣·𝑐𝑜𝑠𝑡𝑠𝑚)O(∣Sp∣·costsm), where 𝑐𝑜𝑠𝑡𝑠𝑚costsm represents the complexity of each space offset calculation; (2) Sort all spatial offsets, th...
