In-relay Power Allocation for Multi-pair Full-duplex Massive-MIMO AF Relay Network

Auxiliary Particle Filtering Over Sensor Networks Under Protocols of Amplify-and-Forward and Decode-and-Forward Relays

“…where the last equality follows from the source-terminal transmission model (4). With the available information on the distribution of channel gains and disturbances, (12) can be used to calculate the p s i,k |λ m i,k . Similar with p r a,i,k |λ m i,k , the accurate integral in ( 12) is difficult to be computed, and therefore we need to use the following formula to approximate p s i,k |λ m i,k :…”

“…where p (r a,j,k |λ m k ) and p (s j,k |λ m k ) can be obtained by re-sorting to (11) and (12), respectively. Setting…”

“…In an AF relay, the received signal from the source is amplified and then retransmitted [36]. For AF relays, the corresponding relay selection and power allocation problems have been discussed in the context of performance specifications such as maximum information secrecy [45], minimum mean-square transmission error [12], and minimum total transmission power [18]. On the other hand, a DF relay demodulates and then decodes the received signal before retransmission.…”
