Sentence examples for relaying Phase from inspiring English sources
The effect of the relaying phase on the performance can also be observed from BER values.
All relays are active and share the relaying phase in two reference schemes.
The transmitted signals are independently generated and the channels encountered during broadcast and relaying phase s are independent.
The values of K 1 and K 2 are chosen according to Section 2. Figure 2 Multiplexing and relaying phase for a given relay node.
The HIR-DFEC algorithm is similar to the IR-DFEC one, see Figure 3, but in the relaying phase the RN sends, besides the check bits, the decoded information bits.
The factor expresses the fact that during the two phases different QAM constellations are used, while indicates that in the relaying phase only a fraction of the first message's length is transmitted.
where represents the complex coefficient of the flat Rayleigh faded BS-UT channel, during the broadcast phase, for the th subcarrier with an average power, denotes the RNi-UT channel during relaying phase, for the th subcarrier with an average power of, in the assumption that the fading over two adjacent subcarriers can be considered flat; that is, is equal to.
The advantage of the IR-DFEC scheme consists of the relatively small amount of time-frequency resources required by the relaying phase, which increase the spectral efficiency, and the possibility to build distributed Hybrid Automatic Repeat Request (H-ARQ) schemes based on this cooperation scheme.
