摘要： A marine air gun (400) generates an acoustic signal in water, for example, during a marine seismic survey. The marine air gun includes digital electronic circuitry (700). The digital electronic circuitry may control an actuator (424) of the marine air gun, digitize and store data from sensors (414, 418) located on or near the marine air gun, send and/or receive digital communications, store and/or output electrical energy, and/or perform other functions. A marine seismic source system (100) that includes multiple air gun clusters (120) may have a separate digital communication link (305, 307) between a command center (106) and each air gun cluster (300a, 300b). Each communication link may provide power and digital communication between the command center and one of the air gun clusters.

摘要： 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.
