At first, Overwatch 2 was to be a completely separate full-priced game with a singleplayer campaign, co-op missions, and multiplayer backwards-compatible with Overwatch 1. We all know how badly the PvE stuff went down, but as we learned more about Overwatch 2 over three years, Blizzard ...
Full size image In MB-OFDM UWB systems, the data of the user are transmitted in the form of data block. One or several data frames are included in a data block. The structure of the data block is shown in Figure2. In the figure,Ais the inter-block interval,Bis the inter-frame inter...
which is a full matrix in the presence of Doppler, will be equalized by means of the conjugate gradient (CG) algorithm[15], whose performance is less sensitive to the condition of the channel matrix than, e.g., a least-squares approach. On the other hand, the convergence rate ...

Full size image Instead of plotting the WER over the SNR, we now want to express the WER as a function of the mutual information per coded bit I_\textsf{c}. We therefore need to compute the MI for each modulation ({{\,\textrm{ld}\,}}(M) \in \{1,6\}) and channel model (AW...
(MC) of the sensing matrix is a good alternative [6]. We utilize the minimum MC as the criterion for optimizing the allocation of pilot patterns to perform channel estimation based on CS. However, it is unrealistic to blindly search the optimal pilot pattern in the actual communication system...
In OFDM-based space division multiple access (SDMA) systems, multiple users are served by a multiantenna base station simultaneously on the same frequency resources. In the uplink, each user's signal may be distorted by an independent carrier frequency o
Full size image We focus in this section on channel estimation for MB-OFDM UWB systems. There are two main methods: the first is based on the channel estimation sequence (CES) of the PLCP preamble and the second is based on pilot signals insertion into each OFDM symbol. Here, even assumin...
