Sentence examples for symbol frames from inspiring English sources

The presence of cyclic prefix in OFDM isolates successive symbol frames and also allows some tolerance with respect to timing phase offset.

In the FBMC systems, the extended length of the subcarrier filters (equivalently, the prototype filter) results in significant overlap of successive symbol frames.

Moreover, because of the absence of any guard interval between successive symbol frames, the timing phase in FBMC system cannot tolerate any significant offset.

A pulse-position modulation is used, where four sub frames and one guard frame form one symbol frame (4-PPM).

The coefficients are obtained computing the wavelet transform of each symbol framed in its tight bounding box.

The demultiplexer collects n T OFDM symbols (an OFDM symbol frame) and sends each symbol ({s q }) to one of the n T transmit paths.

In order to make the target detection process arrive at a more descriptive representation, a matrix is applied to denote the frequency-domain symbol frame in (25).

The condition N h  ≤ N p ensures that r p (i) contains contributions only from the currently transmitted OFDM symbol frame.

As shown in the figure, for both cases of and, the proposed approach can effectively trace the symbol boundaries and make the symbol frame being synchronized within the scale of step size.

Another CL estimate technique found in [24] is introduced based on the minimization of a combination of cost functions for single-input multiple-output (SIMO) channels where the channel is also assumed to be unchanged during a symbol frame.
