Description: Iterative receiver techniques, multiple-input – multiple-output (MIMO) processing, and
orthogonal frequency division multiplexing (OFDM) are amongst the key physical layer
technologies when aiming at higher spectral efficiency for a wireless communication system.
Special focus is put on iterative detection, decoding, and channel estimation for a MIMO-OFDM
system. After designing separately efficient algorithms for the detection, channel decoding, and
channel estimation, the objective is to optimize them to work together through optimizing the
activation schedules for soft-in soft-out (SfISfO) components.

Description: Soft Decision Bits
The aim of an Equalizer is to estimate the transmitted symbols at the receiver stage, which is more specifically to decide each bit in the symbol being a „ 0‟ or „ 1‟ . A decision formed in a binary way of either 0 or 1 is called a hard decision. Hard decision decoding takes a stream of bits from the threshold detector stage of a receiver, where each bit is considered definitely either „ 1‟ or „ 0‟ . For binary signaling, received pulses are sampled at time intervals ts = nT, and the resulting voltages are compared with a single threshold. If a voltage is greater than the threshold it is considered to be definitely a 1 say regardless of how close it is to the threshold. If it is less, it is definitely a „ 0‟ . This is equal to making a 100 positive decision of a certain bit.-Soft Decision Bits

Description: Complete the integration of all the blocks using source and convolutional coders on the previous slide. Next add modulation and AWGN channel. Now show the working of the whole system by showing the Huffman coded dictionary, channel coded data, constellation diagrams for the modulation. Additionally, show the constellation diagram (using scatterplot) after AWGN channel before decision and after decision, decoded channel code data and decoded Huffman data.
Apply both soft and hard Viterbi decoding for decision at the receiver. The data set to be used is based on same initial data {1, 2, 3, 4, 5} with random arrival to make total bit count equal to 1e6.
