Based on concatenating iteration, multiple complementary sequence sets which are orthogonal each other are proposed. Each complementary sequence set of the constructed multiple sets is composed of multiple complementary sequences with each complementary sequence containing a flock of element sequences. The complementary sequences in the same complementary sequence set possess ideal auto-correlation...
Based on any two orthogonal matrixes with the number of rows of one matrix equal to the number of columns of another matrix, a novel set of complementary sequences is proposed. The constructed complementary sequences with each sequence including a flock of element sequences have ideal auto-correlation and cross-correlation properties, where the correlation function of a complementary sequence is equal...
A class of multiphase sequences with periodic odd-shift orthogonal properties is presented. The constructed sequences are based on interleaved DFT matrix and their periodic autocorrelation function (ACF) is 0 for all odd shifts. These sequences can be divided into multiple groups. The intra-group periodic cross-correlation function (CCF) values are alternately zero and the inter-group periodic CCF...
In a wireless communication system, sequences with impulsive periodic autocorrelation correlation, known as perfect sequences, are widely applied to, e.g., such sequences can be made use of as synchronous signals. In this paper, based on interleaving technique, a novel construction of distinct perfect polyphase sequences (PSs) is presented. The proposed perfect PSs possess the same phase alphabet...
In this paper, we present a novel set of frequency hopping (FH) sequences which have few-hit zone (FHZ). Different from the existing FH sequences with no-hit zone (NHZ), the proposed set not only has good correlation properties within FHZ, but also has a large family size. The quasi-synchronous frequency hopping code division multiple access (QS-FH-CDMA) systems using such FH sequences with FHZ can...
Time-hopping (TH) sequences play an important role in time-hopping ultra wideband (TH-UWB) communication systems. The proper measure for the performance of TH sequences is time-hopping correlation function (TH-CF). For TH sequences with a long period, the total number of computations to implement directly TH-CF will be huge, and it will increase very rapidly as the period increases. Hence, it is of...
