چکیده
Power Line Communication (PLC) serves as a medium for communication over power lines, utilizing the existing grid information transmission. It offers low-cost, highly scalable signal transmission method and has potential to become preferred technology providing broadband in smart homes, offices, grids. However, noise line channel, especially impulse noise, seriously affects quality of PLC. In this paper, we establish an OFDM-PLC system with higher-order modulation polar codes. The QAM or APSK technique is employed increase rate performance analyzed. To combat PLC first model it using superposition multi-damping sinusoidal functions then introduce coding scheme suppress system, thereby improving reliability. Simulation results verify that proposed based on can improve Bit Error Rate (BER) channel under interference.

M-ary amplitude shift keying OFDM system
Coherent M-ary ASK is proposed to be used in OFDM systems. The frequency separation between subcarriers is only 1/2T instead of 1/T. With a slightly wider bandwidth, an M -ary ASK-OFDM can achieve the same BER of M-ary QAM-OFDM and a better BER than that of MPSK-OFDM. The M -ary ASK-OFDM has the same Peak-To-Average-Power Ratio (PAPR) as that of the M-ary QAM-OFDM. The MASKOFDM can be implement...
متن کاملConstruction and Performance of q-ary Turbo Codes for use with M-ary Modulation Techniques
This paper describes a construction technique for q-ary Turbo Codes that computes good recursive systematic convolutional q-ary constituent codes with constraint length ν ≤ 5 for q = 2, m = 2 and 3. The construction technique, based on the algorithm in [5], determines the codes with maximum di for i = 2, 3, and 4 and minimum codeword multiplicity, where di is the minimum weight of all code sequ...

متن کاملAn efficient secure channel coding scheme based on polar codes
In this paper, we propose a new framework for joint encryption encoding scheme based on polar codes, namely efficient and secure joint secret key encryption channel coding scheme. The issue of using new coding structure, i.e. polar codes in Rao-Nam (RN) like schemes is addressed. Cryptanalysis methods show that the proposed scheme has an acceptable level of security with a relatively smaller ke...
متن کاملM-ary Chaotic Sequence Based SLM-OFDM System for PAPR Reduction without Side-Information
Selected Mapping (SLM) is a PAPR reduction technique, which converts the OFDM signal into several independent signals by multiplication with the phase sequence set and transmits one of the signals with lowest PAPR. But it requires the index of the selected signal i.e. side information (SI) to be transmitted with each OFDM symbol. The PAPR reduction capability of the SLM scheme depends on the se...
