OFDM channel estimation code comb pilot
no vote
OFDM channel estimation simulation code based on comb pilot. According to the different arrangement of pilot sequence, the pilot structure can be divided into three types: dressing pilot, block pilot and lattice pilot. In comb pilot type, pilot signals are periodically placed on the subcarriers of each OFDM symbol, and then these pilot signals are used for frequency domain interpolation to estimate the channel along the frequency axis.
