slot in turn consists of a number of OFDM symbols which can be either seven (normal cyclic prefix) or six (extended cyclic prefix). Figure 3 shows the frame structure for LTE in FDD mode (Frame Structure Type 1). The useful symbol time is Tu = 2048 ⋅ Ts ≈ 66.7 μs. For the normal mode, the first symbol has a cyclic prefix of length TCP = 160 ⋅ Ts ≈ 5.2 μs. The remaining six symbols have a cyclic prefix of length TCP = 144 ⋅ Ts ≈ 4.7 μs. The

2006-04-17 This guard internal is referred as cyclic prefix (CP). This is kept greater than delay spread of the channel to avoid ISI. Following are basics of cyclic prefix (CP): • Zeros used in the guard time can alleviate interference between OFDM symbols. Cyclic Prefix Similar to Mobile WiMAX, LTE also implements cyclic prefix (CP) to form a symbol Data symbol periods become shorter as the data rate becomes larger since the symbol period is inversely proportional to the data rate or 1/(data rate) As the symbol period shortens, the 2013-06-04 The cyclic prefix is created so that each OFDM symbol is preceded by a copy of the end part of that same symbol.

So the length of prefix of the first symbol is 5.208 microseconds and the length of the other per symbol is 4.6875 microseconds. 2) Extended CP (long CP) The Cyclic prefix type parameter controls whether the block expects normal or extended CP. When the block operates at a maximum sample rate of 30.72 MHz, it assumes that each symbol is 2048 samples plus the cyclic prefix size associated with that rate. A resource block is a smallest unit of resource allocation in LTE. Resource element is the smallest unit of resource block. It is 0.5ms duration with 12 subcarriers in 1 OFDM symbol.

Adding cyclic prefix to the transmitted signal to create a signal that appears to be just like circular convolution and this is done by copying the last part of each OFDM symbol to the front of each symbol with the length of a guard interval, to form a cyclic prefix (CP).

LTE 6 symbols Two types of Cyclic Prefix supported by LTE: 1) Normal CP (short CP) As shown above, if Normal CP is used in LTE and then there are 7 symbols in 1 slot(0.5 milliseconds). So the length of prefix of the first symbol is 5.208 microseconds and the length of the other per symbol is 4.6875 microseconds. 2) Extended CP (long CP)
