The cyclic prefix, although elegant and simple, is not entirely free. It comes with both a bandwidth and power penalty. Since redundant symbols are sent, the required bandwidth for OFDM also increases. Similarly, an additional symbol must be counted against the transmit-power budget.

In general, the cyclic prefix should be at least as long as the delay spread that you expect from your channel. II. CYCLIC-PREFIX REVIEW Figure 2(a) shows the input stream divided into blocks of length M . The L symbols at the end of each block (where L = channel order) are copied into the beginning of that block, to form the cyclic prefix [3] (thin lines inFig.

This extended waveform is windowed by pointwise multiplication in the time domain with a raised cosine window, which applies a taper to the first N and last N samples, with all other values being 1. So presumably it follows that > a longer cyclic prefix, allows the sub-carriers to be spaced closer > together. No. T is the length of the OFDM symbol before the cyclic prefix has been added.

On synchronization in OFDM systems using the cyclic prefix

Key Factors to De. Multi Cyclic Prefix-ed OFDM A cyclic-prefixed OFDM (CP-OFDM) transceiver architecture is typically implemented using inverse discrete Fourier transform (IDFT) and discrete Fourier transform (DFT) blocks (refer Figure 13.3). In an OFDM transmitter, the modulated symbols are assigned to individual subcarriers and sent to an IDFT block.
