Sentence examples for reference symbols for from inspiring English sources

The transmission of an OFDM signal requires also the transmission of a cyclic prefix (CP) to avoid inter-symbol interference and the reference symbols for channel estimation.

These methods provide low-complexity and require no signaling overhead by the exploitation of existing reference symbols for signaling overhead reduction.

There are seven symbols (normal CP length) in a slot and reference symbols for DL are placed at either first and fourth OFDMA symbols or at second and fifth OFDMA symbols.

Four resource elements in each PRB are used for downlink reference symbols.

If we notice that the complex D-QPSK symbol zm,l,k for the phase reference symbols has fixed values, the exponential terms in gk,l(t) can be interpreted as the Fourier transform coefficients.

The theoretical lower bound on data-aided (DA) frequency estimation error for bursts transmissions containing reference symbols is known to decrease if the reference symbols are distributed throughout the burst.

In Release 10 LTE, different RSs are defined for channel estimation, namely CSI reference symbols (CSI-RS) and demodulation reference symbols (DM-RS).

By including reference symbols in the optimization interval, i.e., applying the same phase rotations for both reference symbols and data symbols, the effects of the phase rotations can be absorbed in the channel estimates, or the phase rotation can be detected (see Section 3.5) and its effect can be removed at the receiver.

Reference symbols: ■ Foreman, Hall, ▲ CoastGuard, and ● Soccer.

This means that the signal for the PRS can be extracted from the received T-DMB signal as shown in Figure 7, and the two dotted lines represent the beginning and closing of the IF signal corresponding to the PRS. Figure 7 Actual IF signal for a phase reference symbol.
