Description: A random stream of bits the size of the desired transport block undergoes
Downlink Shared Channel (DL-SCH) coding to rate match the transport block
to the available PDSCH bits. Scrambling, modulation, precoding and layer
mapping are then applied to form the complex PDSCH symbols. AWGN is added
to these symbols after which channel decoding and demodulation are
performed to recover the transport block. Using the recovered transport
block a BER curve is plotted for a given range of SNR values.

Description: LTE小区搜索过程是UE和小区取得时间和频率同步，并检测小区ID的过程。E-UTRA系统的小区搜索过程与UTRA系统的主要区别是它能够支持不同的系统带宽（1.4~20MHZ）。小区搜索通过若干下行信道实现，包括同步信道（SCH）、广播信道（BCH）和下行参考信号（RS）。SCH又分成主同步信道（PSCH）和辅同步信道（SSCH），BCH又分成主广播信道（PBCH）和动态广播信道（DBCH）。-LTE cell search procedure the UE and the cell made time and frequency synchronization, and detects a cell ID of the process. The main difference between the E-UTRA system, a cell search procedure and UTRA system is its ability to support different system bandwidths (1.4 ~ 20MHZ). The cell search by a number of downstream channels to achieve, including the synchronization channel (SCH), a broadcast channel (BCH) and the downlink reference signal (RS). SCH is divided into a primary synchronization channel (PSCH) and secondary synchronization channel (SSCH), BCH is divided into a primary broadcast channel (PBCH) and dynamic broadcast channel (DBCH).
