Construction of Hexagonal-8-QAM Constellation and Code for OFDM
نویسنده
چکیده
A construction of hexagonal shaped 8-point QAM called H8QAM is shown. It is shown that H8QAM constellation outperforms the conventional rectangular constellation and 8-PSK. Further, we construct H8QAM sequences having low peak-to-mean envelope power ratios (PMEPR) from QPSK Golay sequences. Various upper bounds on peak envelope powers of these sequences are evaluated.

Hexagonal-8-QAM Constellation with Low PMEPR codes
A construction of hexagonal shaped 8-point QAM called H8QAM is shown. H8QAM constellation outperforms the conventional rectangular constellation and 8-PSK. Furthermore, construction of H8QAM Golay sequences having low peak-tomean envelope power ratios (PMEPR) from two QPSK Golay sequences is presented. Various upper bounds on peak envelope powers of these sequences are evaluated.

OFDM is a powerful multicarrier transmission technique used extensively for wireless applications. High PAPR is one of the deleterious problems of OFDM. This paper reviews basic OFDM system and PAPR problem associated with it. Also, the construction of M-QAM particularly 16-QAM sequences using QPSK Golay sequences over 4 is conferred. It is elucidated that a 16-QAM constellation can be writte...
متن کاملRecursive construction of 16-QAM Super-Golay codes for OFDM systems
In this paper, the Peak to mean Envelope Power (PMEPR) of the OFDM codes generated from an 16-QAM constellation is discussed. Maintaining the same level of error correction properties, these codes achieve higher information rate. A new set of 16-QAM Golay sequences having PMEPR bounded up to 3dB is defined. Many recursive structures are found to generate Super Golay sequences. The recursive alg...
متن کاملConstruction of non-square M-QAM sequences with low PMEPR for OFDM systems - Communications, IEE Proceedings-
The author considers the use of coding to reduce the peak-to-mean envelope power ratio (PMEPR) for orthogonal frequency division multiplexing (OFDM) systems. Most of the existing schemes that use coding for PMEPR reduction assume a PSK constellation. The author presents the construction of non-square M-QAM symbols from a combination of QPSK and BPSK signals when M=2 and n is an odd number. By u...
