“…Hence, for M = 8 PC, we can infer that, from δ = 1 to δ = 2, high rates can be attained while still achieving spectral shaping. It should however be noted that the obtained results are specific for cases of δ > 1, where columns h = [0, 7], h = [0, 1, 7] and h = [0, 1,6,7]. Any other columns combination selected for removal will result into spectrums with notches that are completely different from those in Fig.…”

In digital transmission systems that involve pulse amplitude modulation (PAM), channel coding is useful for spectral shaping by concentrating the frequency energy of the transmitted information towards a predetermined range of the frequency spectrum, or making it have low power content at such frequencies, so as to suit the frequency characteristics of the communication channel. We thus present a permutation coding system with injections that can exhibit spectral shaping at rational sub-multiples of the symbol frequency. We also present a mathematical expression that allows for the prediction of low energy positions in the codebook's spectrum. Upper and lower bounds for the low energy spectrum were also determined. Due to the way the injections are introduced, it gives the scheme an advantage of achieving higher symbol rate, when compared with conventional permutation coding systems.

“…Furthermore, the codes presented are MDS and contain a subset of codewords of size p 2 − p, which is the largest subset of codewords of length p having p distinct symbols [4]. Finally, MDS codes can be seen as optimum codes for correcting erasures since they satisfy λ = d − 1 = n − k, i.e., MDS codes allow for the maximum possible number of erasure patterns to be corrected for a given value of n − k. We remark that the code construction proposed in this Letter contributes a practical solution for systematically constructing permutation arrays for application of permutation coding in power-line communication [9,10]. Power-line communications remains an area of growing scientific interest and recently has gained an important input coming from smart grid applications [11].…”

A class of p-ary (n, k, d) cyclic codes with block length n = p, dimension k = 2 and minimum Hamming distance d = n − k + 1 = p − 1 is introduced, where p denotes a prime. These codes are maximum distance separable repeated-single-root cyclic codes with generator polynomial g(x) = (x-1) p-2. The codebook has size p 2 and contains a subset S of p(p-1)codewords having p distinct symbols each. The size of S is maximum for the given parameters and its codewords are useful for applications of coded modulation in power-line communications.

“…According to Vinck, PCs in combination with MFSK are capable of handling the types of noise associated with narrowband PLC channels. This then gave inspiration for more research works on PCs, some of which are reported in [6][7][8][9][10][11][12][13][14][15][16].…”

Minimum Hamming distance, d m , has been widely used as the yardstick for the performance of permutation codes (PCs). However, a number of PCs with the same d m and cardinality can have different performances, even if they have the same distance optimality. Since PC is a robust channel coding scheme in power line communications applications, we present a simple and fast ranking method that predicts the relative performance of PCs, by using the information extracted from their Hamming distance distributions. This tool is useful for selecting an efficient PC codebook out of a number of similar ones.
