Subcarriers

This program plots sensitivity of OFDM sub carriers with Carrie frequency offset(CFO). Presence of CFO changes position of sub-carriers. Platforms: Matlab

As the power needed to transmit a certain number of bits ina subcarrier is independent of the numbers of bits allocated toother subcarriers, it turns out that a greedy approach is optimal.A greedy algorithm assigns bits to the subcarriers one bit at atime, and in each assignment, the subcarrier...

In this document, the problem of OFDMA multi-user resource allocation based on MMSE channelestimation is considered. Maximization of system capacity, based on available error-free instantaneousestimated channel state information at the transmitter, is the goal. Optimal power distribution... Platforms: Matlab

if we have 16 subcarriers let us dedicate r1,r2,r3 and r4 as PRC or peak reduction carriers and transmit on x1:x12 so when x1:x12 summation creates a peak, a combination from r1,r2,r3 and r4 creates an anti peak but not the exact anti peak or the output would be a flat signal from which data can...

Platforms: Matlab

we use (phase rotation)by multiplying all the subcarriersin the sum by different phases to create a new data vector, not only that but also as we don't know the optimum phases to give the best PAR we create more than one vector and then select the optimum. Platforms: Matlab
