    Based on one-dimensional quadratic congruence code performance of frequency-hop time-spread codes of QCC/QCC and QCC/OOC was analyzed. By calculating the number of hits of codewords in different situation, the mean value of cross-correlation is deduced, and the bit error ratio for two types of two-dimensional codes of QCC was simulated and compared. The simulation results show that compared with QCC/QCC, the performance of QCC/OOC is better and capacity is larger, but the number of frequency-hop chips is larger when the code length is determined. When the capacity of code family is determined, the performance of QCC/QCC with large value of ρ is better, but code length of it is longer.
