A transmitter includes an encoding module, an adaptive hierarchical signal mapping module and a transceiver module. The encoding module receives an input signal and encodes the input signal. The input signal includes data to be transmitted. The adaptive hierarchical signal mapping module modulates the encoded signal according to one or more hierarchical level distance ratios to obtain modulated symbols. The hierarchical level distance ratio defines distances between the modulated symbols. The transceiver module generates a radio frequency signal according to the modulated symbols and transmits the radio frequency signal to an air interface.

In an adjustable voltage examining module, while a logic tester issues an input signal to an audio module under test, upper/low-threshold reference signals are simultaneously issued to an adjustable voltage comparing circuit. While the adjustable voltage comparing circuit receives a signal under test returned by the to-be-examined audio module after a while, the adjustable voltage comparing circuit loads both an high-threshold reference voltage and a low-threshold reference voltage respectively indicated by the reference upper/low-threshold signal so as to compare both the upper and low-threshold reference voltages with the signal under test. Therefore, while the signal under test is examined to acquire a voltage level between voltage levels of the upper and low-threshold reference signals, precise operations of the audio module under test are assured, and time wasted by continuously-issued interrupt is saved.

A base station (BS), a subordinated station (SS) and the transmission methods thereof for use in a multi-input multi-output (MIMO) network are provided. The BS stores resource allocation information about the MIMO network and an SS list, and generate a super frame according to the resource allocation information and the SS list. The super frame comprises a pilot pattern which comprises a plurality of pilots and data. The BS and SS both considers the pilot pattern as an identifier of the SS. When there are communications occurred between the BS and the SS, the BS/SS will confirm whether the pilot pattern of the super frame matches the identifier of the SS to reduce interference from other stations in the MIMO network.
