Abstract: A combined architecture of Long Term Evolution (LTE) downlink data channels with optimised transmitter and receiver is proposed in this paper. This work mainly focuses on the downlink physical channels namely Physical Downlink Shared Channel (PDSCH), Physical Broadcast Channel (PBCH) and Physical Multicast Channel (PMCH) in Single Input Single Output (SISO), Multiple Input Single Output (MISO) and Multiple Input Multiple Output (MIMO) configurations. The data from higher layer are scrambled, modulated, layer mapped, precoded and mapped to resource elements in the transmitter. At the receiver, demapping from resource elements, decoding, delayer mapping, demodulation and descrambling have to be done by every physical channel. Simulation of these channels is carried out using ModelSim 6.4a and synthesis and implementation are done using PlanAhead 13.4 in Viretx-5 device. Implementation results include Register Transfer Level (RTL) design, power estimation, resource estimation and Field Programmable Gate Array (FPGA) editor.
