摘要： A method for storage for complex numbers that employs a shared exponent field is disclosed. Rather than each floating point component of an complex number having its own distinct signed mantissa and exponent fields, each component includes a distinct signed mantissa field and shares an exponent field, thereby increasing the possible size of each distinct signed mantissa field by as much as one half the number of bits formerly employed to store a single distinct exponent field.

摘要： Provided is dual mode operation by a communicating device in wireless network. The communicating device selects a radio frequency (RF) channel and a physical layer type. The communicating device processes signals received via the selected RF channel based on the selected physical layer type. The communicating device may determine whether a beacon frame has been detected base on the signals that were received via the selected RF channel and processed based on the selected physical layer type. When a frame is not detected, the communicating device may determine a signal energy level for the received signals.
