modules of GNU radio.

OFDM (IEEE 802.11a standards) and Channel Estimation: University of Michigan Jan-April 2013

• Tx: Used BPSK and QPSK modulations,cyclic prefix coding and IFFT at the transmitter

• Employed (40, 16) Product codes as an error control optimization scheme.

• Channel: Prepared a channel model with Doppler Effect for moving vehicles and office environments in

the presence of Rayleigh Fading.

• Pilot Insertion: Compared Comb, Scattered and block type pilot arrangements for channel estimation.

• Rx: Used BPSK and QPSK demodulation and detection using FFT, cyclic prefix removal and filtering

the noise components to decode the messages.
