Abstract:
1. A jitter correction apparatus comprising: an output unit generating, in a MAC (Medium Access Control) layer, when data except for a beacon is received in a physical layer, transmission data based on said data received and outputting said transmission data through an interface between said MAC layer and a LINK layer to said LINK layer; a beacon detection signal output unit outputting, when data that is a beacon is received in said physical layer, a beacon detection signal from said MAC layer to said LINK layer; and a correction unit using said beacon detection signal to correct, in said LINK layer, a clock frequency generation function of said LINK layer, wherein said beacon detection signal output unit outputs, from said MAC layer to said LINK layer, said beacon detection signal with higher priority given thereto over said transmission data, without queuing said beacon detection signal together with said transmission data in said interface.
