摘要： In a local wireless communication system, a reception signal including an STF (short training field) in which a plurality of patterns are repeatedly transmitted is received, the STF including a first number of STF patterns and a second number of STF patterns, the second number of STF patterns having an opposite code to that of the first number of STF patterns. In a first frequency offset estimation and correction process and a second frequency offset estimation and correction process, frequency offset estimation is performed on a plurality of STF patterns to acquire a phase error of each sample constituting the STF patterns, and the frequency of the STF patterns is corrected based on the acquired phase error. Cross correlation is performed on a predetermined number of STF patterns, among a plurality of STF patterns output subsequent to the frequency offset estimation and correction, to detect frame timing.

摘要： Provided are a system and a method for allocating wireless resources in a WPAN. The system includes an MAC layer. The MAC layer divides a superframe into a predetermined number of groups, estimates the number of MASs requested by the MAC client and the number of required consecutive MASs, and allows the consecutive MASs to be distributed and allocated for each divided group. With this structure, adjacent clients can use a common MAS and thus a minimum resource is allocated to the adjacent clients in a WPAN.
