Wide-Bandwidth, High Frame Rate Electrical Impedance Tomography / Spectroscopy - a Code Division Multiplexing (CDM) Approach
نویسندگان
چکیده
We present a proposal and proof-of-concept, experimental results for a new type of electrical impedance tomography / spectroscopy system that makes use of code division multiplexing to achieve two important technological advances. Assigning each channel an orthogonal code allow all the impedance measurements to be made simultaneously in time, thereby increasing the frame rate; and the use of pseudorandom input signals allows a very wide range of frequencies to be sampled simultaneously in each channel.

OFDM code-division multiplexing in fading channels
In this paper, orthogonal frequency-division multiplexing–code-division multiplexing (OFDM-CDM) is presented and investigated as alternative to conventional OFDM for high rate data transmission. An additional multipath diversity gain can be obtained with OFDM-CDM by spreading each data symbol in frequency and time. The optimum reliability information for the Viterbi decoder is derived for OFDM-...
متن کاملOrthogonal Code-Multiplexed Frequency-Domain Single-Carrier Spread Spectrum
Abstract The authors have proposed a frequency-domain single-carrier spread spectrum (SC-FDSS) transmission technique, which achieves better bit-error rate (BER) and better power amplifier-dependent energy efficiency comparing with time-domain spread spectrum (TDSS). However, its wider transmission bandwidth leads to low spectrum efficiency, implying that a multiplexing technique is necessary. ...
متن کاملSpace frequency block codes and code division multiplexing in OFDM systems
Abstract— This paper investigates different diversity concepts for OFDM systems. These are space frequency block codes (SFBC) and code division multiplexing (CDM). The performance of both and of combinations of both is compared for coded OFDM systems in a Rayleigh fading channel. The SFBCs and CDM applied in this paper have in common that they have no rate loss and thus do not decrease the band...
متن کاملA Frequency Scheduling Method for MC-CDM
Multi-carrier code division multiplexing (MC-CDM) is one of promising multiplexing techniques for fourth-generation mobile downlink communications systems, where high data rate services should be provided even for high speed-cruising mobiles. For MC-CDM-based packet communication, a frequency scheduling method, which adaptively assigns different sub-carriers to different users, is proposed. Thi...
متن کاملAn Efficient Scheme for PAPR Reduction of OFDM based on Selected Mapping without Side Information
Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...
