Using Costas Arrays to Construct FrequencyHop Patterns for OFDM Wireless Systems

摘要

Throughput of OFDM wireless systems depends onrnthe ability of applied Frequency Hopping codes to minimize therninter- and intra-cell interference. We provide a construction ofrnan algebraically constructed Frequency Hop code family thatrnachieves these requirements. The construction is based on thernproperties of Costas arrays. Examples of the codes and how theyrnare assigned to users,and proofs of theorems are also given.
