摘要： This invention relates to the field of communication systems. More particularly, this invention is a method and system for detecting the presence of a wireless local area network. With reference to Fig. 3, the WLAN front end (204) comprises an RF filter (302), a low noise amplifier (306), a mixer (310), a phase-locked loop circuit (314), a band pass filter (318), an automatic gain control circuit (322), and an in-phase and quadrature demodulator (326). In operation, an RF signal propagating in a wireless local area network frequency band is coupled to the low noise amplifier (306) from the RF filter (302).

摘要： A decoder and decoding method that incorporates an improved Chien search cell (1100), in which memory requirements and delay are both reduced. The prior art Chien search cell processes the error location polynomial coefficient in an iterative manner, beginning with an alpha exponent of ‘0’ which is decremented with each clock cycle until the exponent decreases to a value of -j(N-1). In the improved Chien search cell (1100), the value of the alpha exponent begins at a value of -j(N-1)and is incremented with each clock cycle until the exponent reaches 0. Therefore, during the first clock cycle, the polynomial coefficient (1100) is multiplied by a premultiplier (1150), forwarded to a multiplexer (1120), and routed to a register (1130) for storage. On Subsequent clock cycles, the output of the register (1130) is forwarded to another multiplier (1140) and then routed by the multiplexer (1120) back to the register (1130).

摘要： In a network system (100) having a plurality of devices (102) communicating via a network (104), a method (300, 400) and system (100) for providing an emergency signal is provided. In one embodiment, a device (102) is malfunctioning if the device (102) continuously transmits data to the network (104) without proper authorization. Another properly functioning device (102) transmits the emergency signal via an auxiliary channel (108) to the malfunctioning device (102). The auxiliary channel (108) is a separate channel supporting the transmission of the emergency signal. The malfunctioning device (102) receives the emergency signal and disables itself in response to this signal.
