Methods, systems, and devices are described for mitigating an unwanted increase in a coding rate of a wireless communication signal. A plurality of symbols including a transmitted codeword is received. The plurality of symbols including a first group of data symbols with a first modulation and coding scheme and a second group of data modulated pilot symbols with a second modulation and coding scheme. Applicable demodulation schemes are adaptively switched for each group of the plurality of symbols. The second group of data modulated pilot symbols are used in lieu of pilot symbols. The second modulation and coding scheme is a more reliable modulation and coding scheme than the first modulation and coding scheme.

The present invention relates to an orthogonal frequency division multiplexing wireless local area network (LAN) transmitting/receiving system for providing expanded service coverage, and a method thereof. A first OFDM modulation is performed for an even-numbered time, and a second OFDM modulation is performed for an odd-numbered time. A transmitting frame including a plurality of signal fields according to the first and second OFDM modulation is transmitted. The receiving system determines whether a signal field is repeatedly generated in the frame. If the signal field is not repeatedly generated, corresponding demodulation is performed. If repeatedly performed, the signal field is demodulated by using first bit allocation information and second bit allocation information having a value of the first bit allocation information. A data field is demodulated according to the demodulated signal field.

A test system for testing an array antenna under test with at least two antenna elements comprises a signal generator that generates a test signal, a signal splitter that splits the test signal into a plurality of antenna source signals for the single antenna elements, and a vector multiplier for each one of the antenna source signals, wherein the vector multipliers each adjust the amplitude and/or phase of the respective antenna source signal according to predetermined adjustment parameters and wherein output ports of the vector multipliers are connected to respective ones of the antenna elements.
