Realization of the SISO Architecture for Downlink Data Channels of 3GPP-LTE Using PlanAhead Tool and Virtex-5 Device
Long Term Evolution (LTE) of UMTS Terrestrial Radio Access and Radio Access Network is a Fourth Generation wireless broadband technology which is capable of providing backward compatibility with 2G and 3G technologies. As compared with other promises LTE is able to deliver high data rate and low latency with reduced cost. An efficient and optimized design of LTE channels is one of the key research topics. This paper proposes the SISO architecture for downlink data channels of LTE. At transmitter, a number of steps regarding this design are discussed in this paper, such as scrambling, modulation, layer mapping, precoding, data mapping to resource elements. Similar to this, demapping from resource elements, decoding, delayer mapping, demodulation and descrambling all are discussed at receiver side.
