Embodiment Construction

[0085] The present invention will be further described below in conjunction with the accompanying drawings.

[0086] refer to Figure 1 to Figure 8 , a method for analyzing channel capacity and bit error rate of a single-hop mobile molecular communication model, comprising the following steps:

[0087] The first step is to use the Poisson distribution to approximate the binomial distribution to obtain the number of molecules received by the RN in the current time slot;

[0088] Consider a one-dimensional diffusion molecular communication system consisting of a sender nanomachine TN, a receiver nanomachine RN and a fluid medium, and assume that the environment is large enough so that the boundary does not limit the propagation, TN and RN are separated by a certain distance and located at the same On a straight line; assuming that TN and RN are fully synchronized in time, the molecular transmission time is divided into time slots of the same size, denoted as t=nT s ; Among the...

Abstract

The invention discloses a channel capacity and bit error rate analysis method for a single-hop mobile molecular communication model. The method comprises the following steps of: 1, obtaining the number of molecules received by a current time slot RN by utilizing Poisson distribution to approach binomial distribution; 2, establishing a hypothesis detection channel model of a single-hop moving molecular communication model; 3, obtaining a mathematical expression of the optimal decision threshold Xiopt by adopting a minimum error criterion; and step 4, on the basis of the optimal decision threshold Xiopt, obtaining the optimal channel capacity and bit error rate. Technical support is provided for designing a single-hop mobile molecular communication system with high channel capacity and low bit error rate.

Description

technical field [0001] The invention relates to biotechnology, nanometer technology and communication technology, and is a method for analyzing channel capacity and bit error rate of a molecular communication model of single-hop movement. Background technique [0002] Because molecular communication has characteristics different from traditional communication technologies and is suitable for many specific application environments (such as in the human body), the academic community generally believes that molecular communication based on biological inspiration is one of the most feasible communication technologies for realizing nano-networks. At present, the research of molecular communication mainly focuses on the static molecular communication model, in which the sender nanomachine, relay nanomachine and receiver nanomachine are fixed. In mobile molecular communication, nanomachines are in a mobile state, which is more common in many practical applications (such as drug del...
