Digital-Communications-OFDM-system

In the Digital Communications project, you will investigate the performance of an OFDM-based communication system

Channel coding: (As methods in ChannelCode.m)

• PolarCode
• LinearBlock (the Decoder (Matlab Fun)) (The function decoder matlab and emplemnted decoder)
• ConvolutionalCode (ConvolutionalCode() A flexible func can be designed for any L&n ConvolutionalCode2() fixed n = 2, L=2 faster for our case)

Symbol mapper: (As methods in Modulation.m)

• QPSK
• 16QAM
• 64QAM

Pilot:

• implemented (Not Sure)

Cyclic prefix

• Add Cyclic prefix
• Remove Cyclic prefix

channel

• AWGN (channel.m)
• Multi-path fading (we get h(fixed for one frame) then make the conv and add the noise in channel.m for both SISO & SIMO)

MIMO setups:

• SISO (QPSK-LinearBlock) (run SISO.m)
• SIMO (QPSK-LinearBlock) (run SIMO.m) -we can Now Use the Selection Combining & The MRC (Just edit the selc to "MRC" Or "SC")
