Sentence examples for receiver feeds from inspiring English sources

As the time-frequency channel matrices H[k](n) are correlated, it is not necessary that the receiver feeds back the channel at each time-frequency slot.

With MIMO precoding, the receiver feeds back the index of the codeword in a codebook to the transmitter; this codeword is then applied as the precoder.

We consider Chase-type ARQ: When the decoding outcome is erroneous at ARQ round k, the receiver feeds back a negative acknowledgment (NACK) message, then the transmitter completely retransmits chip-matrix X' in the next round.

The assumption that the channel states take values from discrete sets is based on two observations: (1) In practice, the channel gains are estimated by transmitting known pilots from the transmitter to receiver (a base station in case of uplink scenario), and then the receiver feeds back the estimated value of channel gains up to some precision level.

And secondly, the one which maximizes ∏ i = 1 d max w i, being w i the nonzero eigenvalues of H H H. The phases to be used are taken from 2 πk K, and thus, the receiver feeds back the index k ̂ that k ̂ = arg max k ∈ 1, 2, ⋯, K det H H H h j, i → h j, i × e j 2 πk K. (4).

The pilot was sent using these two vectors alternately, and the receivers fed back the preferred vector according to the signal strength decision with one bit; the transmitter updates the two weighted vectors according to the feedback.

Receiver-k feeds the estimated (measured) Φ k back to Transmitter-k; Transmitter-k calculates the reduced Φ k red as: Φ k red, ( t ) = Φ k ( t ) − P k ( t − 1 ) d k, k − ρ χ k, k H k, k T k ( t − 1 ) T k ( t − 1 ) † H k, k † = ∑ j ≠ k P j ( t − 1 ) d k, j − ρ χ k, j H k, j T j ( t − 1 ) T j ( t − 1 ) † H k, j † + N t σ n 2 I N r x N r ; (12).

The receiver then feeds back this information to the transmitter/video encoder.

In this scenario, the receiver only feeds back the index of the selected transmit beamformer to the transmitter.

The receiver (RX) feeds back the index χ representing the AMC mode to the transmitter (TX) for adaptation.

The optimal index mapping strategy for a channel h in this set is for the receiver to feed back an index i such that D ( P i ( N ), h ) ≤ D m a x and D ( P i + 1 ( N ), h ) > D m a x.
