Sentence examples for symbol the frequency from inspiring English sources

In order to simplify the notation, assuming that the channel is static over the duration of a block (i.e., an OFDM symbol), the frequency response between Tx-antenna i and Rx-antenna j over the N c subcarriers during the kth OFDM symbol can be expressed as h ̄ ij ( k ) = h ̄ 0 ij ( k ) … h ̄ N c − 1 ij ( k ) T. (10).

The integer frequency offset (IFO) is estimated according to a cross-correlation function (CCF) computed between the known second symbol and the received symbol in the frequency domain.

where is the index of the OFDM symbol, is the frequency domain th modulated symbol,, and is the total number of subcarriers.

The MC-CDMA system divides the available bandwidth into a large number of narrow subchannels [6 8] and spreads each data symbol in the frequency domain by transmitting all the chips of a spread symbol at the same time, but in different orthogonal subchannels.

By defining the BEM in this way, the resulting channel matrix of the j th OFDM symbol in the frequency domain will admit a slightly different expression than in (5) defined for the single OFDM symbol case: H d ( m, n ) [ j ] = ∑ q = 0 Q W K D { u q [ j ] } W K H D { V L c q ( m, n ) }. (24).

MC-CDMA combines orthogonal frequency-division multiplexing (OFDM) with CDMA to spread the data symbol in the frequency domain.

The number of complex multiplications C is calculated for K/2 processed samples in the time domain which corresponds to one OQAM-OFDM symbol in the frequency domain.

After the removal of the cyclic prefix (CP) and the discrete Fourier transform (DFT), we give the expression of the n th-received OFDM symbol in the frequency domain as U n = C ̲ n H n + W n, (1).

A received OFDM symbol in the frequency domain at the nrth receive antenna can be written as y ~ n r = ∑ n t = 1 N t H ~ n t, n r x n t + n ~ n r, (1).

We study the frequency-selective broadcast channel with confidential messages (BCC) where the transmitter sends a confidential message to receiver 1 and a common message to receivers 1 and 2. In the case of a block transmission of symbols followed by a guard interval of symbols, the frequency-selective channel can be modeled as a Toeplitz matrix.

CFO can be estimated in two stages using P1 and P2 symbols in the frequency domain.
