The primary contribution of GHCM system is that the modulation orders (i.e., α and β) at the transmitter and receiver can be flexibly selected, which can expand the applications over communications (i.e., the security communication and MIMO systems).
It directs a Verizon division, Verizon Business Network Services, to turn over "on an ongoing daily basis" the "following tangible things": All call detail records or "telephony metadata" created by Verizon for communications (i) between the United States and abroad; or (ii) wholly within the United States, including local telephone calls.
1. Case 1: TNFD communications (i) AP initiates the transmission (ii) Any HDN initiates the transmission (iii) Any FDN initiates the transmission 2.
As the short-range communications, i.e., D2D, are more reliable, this paper assumes that Q=2P.
ITS tackles the problem by providing bi-directional M2M communications, i.e., between vehicles and ITS server.
The technique presented in this paper uses clustering in both types of communications, i.e., intra-WBAN and inter-WBAN.
The proposed cluster-based routing in WBAN includes two types of routing in inter-WBAN and intra-WBAN communications i.e., intra-cluster routing, and inter-cluster routing.
Here, we assume that each transmitter is able to perfectly estimate its own channel realizations (coherent communications), i.e., the channels hk,1 … hk,S for transmitter k.
In conventional TDMA-based cooperative communications (i.e., without network coding and multiple-access transmissions), a total of N2 time slots is required to achieve full diversity.
The first kind of uplink communication contains only uplink data, i.e., case ① in Figure2, while the other two kinds of uplink communications, i.e., cases ② and ③ in Figure2, cover both the uplink data and pilot.
We stress that the case of bit-oriented communications, i.e., Q=1 is included as a special case in our definition of the energy efficiency and all results to follow will hold true also for Q=1.
