Peak-to-mean power control in OFDM, Golay complementary sequences, and Reed-Muller codes
We present a range of coding schemes for OFDM transmission using binary, quaternary, octary, and higher order modulation that give high code rates for moderate numbers of carriers. These schemes have tightly bounded peak-to-mean envelope power ratio (PMEPR) and simultaneously have good error correction capability. The key theoretical result is a previously unrecognized connection between Golay ...
متن کاملComplementary Sets, Generalized Reed-Muller Codes, and Power Control for OFDM
The use of error-correcting codes for tight control of the peak-to-mean envelope power ratio (PMEPR) in orthogonal frequency-division multiplexing (OFDM) transmission is considered in this correspondence. By generalizing a result by Paterson, it is shown that each q-phase (q is even) sequence of length 2 lies in a complementary set of size 2, where k is a nonnegative integer that can be easily ...

متن کاملA Performance Comparison of Golay and Reed-Muller Coded OFDM Signal for Peak-to-Average Power Ratio Reduction
Multicarrier transmission system such as Orthogonal Frequency Division Multiplexing (OFDM) is a promising technique for high bit rate transmission in wireless communication systems. OFDM is a spectrally efficient modulation technique that can achieve high speed data transmission over multipath fading channels without the need for powerful equalization techniques. A major drawback of OFDM is the...

OFDM, Reed-Muller, ACI, Golay complementary sequences The performance of OFDM with Reed-Muller encoding and a maximum likelihood decoding algorithm is presented. The example codes are shown to have a tightly bounded peak-to-mean envelope power ratio of at most 3.0dE, .whilst simultaneously enabling good error correction. Using both experimental and simulated results the codes are shown to offer...
